Investigation of granular capillary rising under vertical vibration

The phenomenon of granular capillary rising under vertical vibration provides a novel technical route for hoisting, transporting and collecting granular materials. However, there are still obvious deficiencies in the existing studies of the granular capillary rising behavior, especially the intensive investigation on the effects of gravitational acceleration, horizontal vibration component and particle size distribution are still lacking. To address these problems, the discrete element method is used to numerically simulate the granular capillary rising phenomenon under different operating conditions. The final capillary rising height and average capillary rising velocity of the granular matter are computed and analyzed based on the numerical simulations. The results show that the granular capillarity can also occur under low gravity conditions, and that the final capillary rising height and the average capillary rising velocity first increase and then decrease with the gravitational acceleration. It is also found that the final capillary rising height is insensitive to the variation of horizontal vibrational component, whereas the average capillary rising velocity increases with the augmentation of horizontal vibrational component. Compared with the mono-sized particles, the particles with the same mean size but having a Gaussian size distribution exhibit a maximal capillary rising height at a larger critical tube diameter. Meanwhile, the average capillary rising velocity of the particles having a Gaussian size distribution is faster in the tube diameter range where the granular capillary dynamics for both size distributions is dominated by the jamming effect.

The aspect of the flow around a circular cylinder in a free surface water flow

The purpose of this study is in collection of the basic data for development of the simple flow velocity measurement equipment. A 10mm diameter circular cylinder was inserted into the free surface stream, and investigation of the water surface height and the relationship of the flow velocity which creep up the circular cylinder surface were performed. The experiment performed in the closed circuit water channel apparatus (the range of stream velocity is 0.07 - 0.98m/s) and carried out image-processing measurement using the video recording apparatus. In the insertion depth of various circular cylinders, observation of the height which creeps up the circular cylinder when varying the flow velocity was carried out. As a result, it became clear that the height of the water surface which creeps up by the increase in the flow velocity increases. And it also became clear for the phenomenon not to be based on the insertion depth. It was obtained that measured rising height and the flow velocity is required from Bernouilli's equation using the value. In the measurement, it became clear that 5 or more times of the cylinder diameter are required for the required insertion depth.

ВПЛИВ ФІЗИЧНИХ І ОКЕАНОГРАФІЧНИХ ФАКТОРІВ НА РОЗШИРЕННЯ ЗОНИ ЗАБРУДНЕННЯ КАСПІЙСЬКОГО МОРЯ (ПІВНІЧНО-СХІДНА ПРИБЕРЕЖНА ЗОНА АЗЕРБАЙДЖАНУ)

Aim. Our main goal is to study the spread of pollution caused by natural and anthropogenic factors in the water area of the Caspian Sea, the largest closed basin in the world, according to physical and oceanographic factors. The methodological basis of the article. The article uses methods of processing statistical indicators and selects the Brooks-Koch method to calculate the rise height (∆H0) of wastewater in a stratified environment. Results. In the water area of the Republic of Azerbaijan, the pollution of the Caspian Sea occurs mostly in the Absheron Peninsula. The main reason for this is that the area is rich in oil and gas reserves and there are many oil production enterprises. In addition to natural factors such as wind, temperature and currents, anthropogenic factors also influence the spread of oil-contaminated seawater. As a result of the analysis of the physical and oceanographic factors, we determined that the depth of sewage should be more than 70 meters when it is discharged into the sea. The main reason for this is that the sewage dumped in the depth is mixed with the cold, and with time, heavy bottom currents. As sewage mixed with clean seawater rises to the surface, it continues to mix in the intermediate layers because its weight is heavier than the layer above it. The main reason why this happens only in the Caspian Sea is that the temperature of the sea water increases instead of decreasing with depth. The fact that the turbulent mixing coefficient calculated for the area confirmed in the article is 104-106 shows that the concentration pulsation intensifies with the increase in the diameter of the sewage sludge. This situation creates conditions for the mixing of waste water with the surrounding water. Scientific novelty. The effect of physical and oceanographic factors on the change, expansion and deepening of the area of sewage in the Caspian Sea water area was studied. Also, the turbulent diffusion coefficient of pollution in coastal zones was calculated.

Evaporation of liquids at low temperatures

Ukrainian enterprises annually generate millions cubic meters of mineralized water, which is discharged into surface reservoirs, and millions cubic meters of highly concentrated solutions and suspensions, which are accumulated and stored in special sludge storages. This waste water causes irreparable damage to the environment. A new method for the evaporation of industrial concentrates by fibrous materials with capillary properties was proposed not so long ago. The use of such materials allows an effective, autonomous, cheap, and extremely simple system to be created for the evaporation for various liquids and concentrates.
 The research methodology was as follows. Two graduated cylinders of the same diameter were used in our research. One cylinder was filled with the liquid phase to a certain level and used to control evaporation from the surface of the aqueous medium. In the other, experimental cylinder, a vertical cotton strip was additionally placed (from 1 to 21 layers of fabric). The width of the strip was 5 cm. The length of the strip was 50 cm. The density of cotton was 100 g/m2. The research method was to determine the height of liquid phase capillary rise along the strip of fabric and to evaluate reduction in the volume of liquid that evaporates in both cylinders at set temperatures.
 It was found that in the absence of wind and the distance between the vertically placed strips of 7–15 mm were sufficient to ensure the maximum evaporation intensity. Our long-term experiments in natural conditions confirmed the high efficiency of the proposed method. At an average daily air temperature of 2.3 °C, there was a significant evaporation from the surface of the fabric during the day. In this case, evaporation from the water surface was not observed. It should be noted that the intensity of evaporation under natural conditions depends on a significant number of factors (temperature, wind speed, luminosity, humidity, etc.), so it is difficult to detect a direct relationship between some of them.
 With increase only in the liquid phase temperature, the evaporation efficiency decreased. At a temperature of 20 °C, the laboratory installation (15 layers of cotton strip) increased the evaporation intensity by more than 2 times, at 46 °C by more than 5 times, at 57 °C by almost 3 times, but at 75 °C only by about 67 %. It is obvious that heating of the liquid phase alone less influences the evaporation process from the surface of the fabric strip, which was cooled rapidly in the atmosphere at a much lower temperature. Therefore, to increase the evaporation intensity, it is necessary to increase temperature for all components of the liquid–fabric system.
 A fabric with suitable properties, stretched between two metal racks and immersed into the liquid phase with the lower end, can be used as a simple evaporator.
 Our research has shown that the use of materials with capillary properties in the treatment of liquid solutions allows simple, cheap, and efficient devices to be created for evaporating water and converting liquid waste into a solid phase.

Flow and Heat Transfer of Supercritical CO2 in a Vertical Tube Under Ocean Rolling Motion

Abstract This paper explores the fluid flow and heat transfer behaviors of supercritical carbon dioxide (SCO2) in a tube. The application is utilization of waste heat from a marine gas turbine. The effects of ocean rolling motion on the thermofluid characteristics of SCO2 in a circular tube are numerically investigated based on a verified turbulence model. It is found that the time-averaged heat transfer capacity over a rolling period is improved over static conditions by 7.9%. However, the onset of heat transfer recovery is postponed, and the range of heat transfer deterioration is extended. Under the action of inertial forces due to the rolling motion, heat exchange between cooler/denser and warmer/lighter fluids is enhanced. Secondary circulation is formed when t/tc = 0.325, and the section-averaged heat transfer coefficient is improved by a maximum of 71%. For various periods, a parabolic can be distinctly found in terms of the variation trend of time-averaged heat transfer coefficient, which behaves differently from conventional fluids. Regarding the instantaneous thermal performance, a polarization phenomenon can be observed under severe rolling. With the rise of the layout height, the time-averaged heat transfer performance of the tube increases monotonously, and the maximum increment is 10.64% in studied range.

A Model for Buoyant Tephra Plumes Coupled to Lava Fountains With an Application to the 29th of August 2011 Paroxysmal Eruption at Mount Etna, Italy

AbstractExplosive basaltic eruptions pose significant threats to local communities, regional infrastructures and international airspace. They produce tephra plumes that are often associated with a lava fountain, complicating their dynamics. Consequently, source parameters cannot be easily constrained using traditional formulations. Particularly, mass flow rates (MFRs) derived from height observations frequently differ from field deposit‐derived MFRs. Here, we investigate this discrepancy using a novel integral plume model that explicitly accounts for a lava fountain, which is represented as a hot, coarse‐grained inner plume co‐flowing with a finer‐grained outer plume. The new model shows that a plume associated with a lava fountain has higher variability in rise height than a standard plume for the same initial MFR depending on initial conditions. The initial grain‐size distribution and the relative size of the lava fountain compared to the surrounding plume are primary controls on the final plume height as they determine the strength of coupling between the two plumes. We apply the new model to the August 29, 2011 paroxysmal eruption of Mount Etna, Italy. The modeled MFR profile indicates that the field‐derived MFR does not correspond to that at the vent, but rather the MFR just above the lava fountain top. High fallout from the lava fountain results in much of the erupted solid material not reaching the top of the plume. This material deposits to form the proximal cone rather than dispersing in the atmosphere. With our novel model, discrepancies between the two types of observation‐derived MFR can be investigated and understood.

A Near-Real-Time Method for Estimating Volcanic Ash Emissions Using Satellite Retrievals

We present a Bayesian inversion method for estimating volcanic ash emissions using satellite retrievals of ash column load and an atmospheric dispersion model. An a priori description of the emissions is used based on observations of the rise height of the volcanic plume and a stochastic model of the possible emissions. Satellite data are processed to give column loads where ash is detected and to give information on where we have high confidence that there is negligible ash. An atmospheric dispersion model is used to relate emissions and column loads. Gaussian distributions are assumed for the a priori emissions and for the errors in the satellite retrievals. The optimal emissions estimate is obtained by finding the peak of the a posteriori probability density under the constraint that the emissions are non-negative. We apply this inversion method within a framework designed for use during an eruption with the emission estimates (for any given emission time) being revised over time as more information becomes available. We demonstrate the approach for the 2010 Eyjafjallajökull and 2011 Grímsvötn eruptions. We apply the approach in two ways, using only the ash retrievals and using both the ash and clear sky retrievals. For Eyjafjallajökull we have compared with an independent dataset not used in the inversion and have found that the inversion-derived emissions lead to improved predictions.

Enhanced capillary performance of grooved nanocarbon foams as wicks for heat pipes

An effective heat pipe needs a great amount of working liquid to be moved quickly from the cold end to the hot end. That is why capillary performance works as a critical factor to evaluate the potential of a wick for high-efficient heat pipes. However, good capillary performance only means that the liquid can be transferred quickly; the amount of liquid transferred during capillary rising also needs to be taken into account. In this work, novel grooved nanocarbon foam (GNCF) wicks were fabricated with good capillary performance and a large capillary rise amount. Grooves with different numbers, depths, and widths were formed on the nanocarbon foams (NCFs) and the effect of these factors on the capillary performance was studied. The results indicate that the groove is beneficial to improve the capillary performance of NCFs due to the enhanced permeability and feeding effect. The capillary performance is achieved with a capillary rise height of 45 mm in 14 s. It is 2.5 times as high as that of the NCF and better than some other published results. Moreover, because the GNCFs have a superhigh porosity of 0.99, they are capable to transfer much more working liquid per time than other wicks with similar capillary performance.

Capillary rise height of sulfate in Portland-limestone cement concrete under physical attack: Experimental and modelling investigation

Capillary rise is a dominate mechanism for the subsequent salt crystallization damage on concrete structures partially exposed to sulfate bearing environments. The aim of this study is to assess the capillary rise height of sulfate (h) in Portland cement (PC) and Portland-limestone cement (PLC) concretes under physical attack. The impacts of limestone contents (0 wt%, 10 wt% and 30 wt%) and water-to-binder ratios (w/b of 0.4 and 0.6) on the pore structures and sorptive property of concrete specimens were investigated. Results show that the effects of limestone content on the capillary rise heights, pore structures and sorptivity of PLC-based concrete specimens differed from different w/b ratios, as a consequence from the competition mechanism between filler effect and dilution effect due to the incorporation of limestone. The heights of efflorescence zone in PLC-based concrete specimens were found to be closely related to their volumes of capillary pores, while those of subflorescence zone only exhibited slight fluctuation at varying compositions. The time-dependent evolution of h can be divided into two stages and almost 35.7%–46.5% of the final height were reached in the first month (the fast increase stage). The capillary rise height h predicted by the modified model demonstrated good agreements with those obtained from experiments, when compared to other prediction models.

Performance evaluation of indigenous floppy sprinkler irrigation system for various crops water management

Freshwater resources are a natural blessing and vital to life. Water is required in many aspects of life due to its importance in the economy. A Floppy sprinkler system (FSS) is an innovative and unique method for pressurizing irrigation. This method has multiple applications other than traditional methods, which can overcome farmer's issues to adopt the high-efficiency irrigation system. The performance evaluation of two types of floppy sprinklers (imported and indigenous) was the primary objective of this research. Three parameters, application efficiency of the low quarter (AELQ), distribution uniformity (DU), and uniformity coefficient (CU), were evaluated under different levels of riser height and operating pressures. A portable testing bench was designed to determine these parameters and the overall performance of FSS in the agriculture field. The system operated at a different pressure range from 1.5 to 4 bar and riser heights 10ft, 12ft, and 15f for both sprinklers. The results revealed that the system achieved maximum CU, DU, and AELQ at the operating pressure of 2.5 bar and riser height of 10 ft for both types of floppy sprinklers. The corresponding values of CU, DU, and AELQ were 84.5%, 70.7%, and 87.0 % for imported and 82.2%, 67.7%, and 82.5% for indigenous FSS. An overlap simulation model was used to achieve a high percentage of system performance. The results declared that the overlapping between sprinklers should be more than 65% to avoid water losses and minimize the overall system cost.

Capillary rise in polydisperse porous media and its modelling

The capillary effect in polydisperse porous systems of soils and sediments is discussed. Its quantitative assessment is based on a physically–based model of capillary rise, depending on the parameters of the dispersivity of soil particles, the soil bulk density and the density of its solid phase, wettability and the amount of strongly bounded water. In contrast to the well–known Jurin’s law, the model takes into account polydispersity and variation in pore size under the influence of the soil bulk density. The model adequately predicts the height of capillary rise both in artificial monodisperse porous systems (granulometric fractions) and in real soils with particles of different sizes from 0.006 to 1 mm. It can be used to calculate the effect of capillarity in soils and intelligent soil design with capillary barriers.

A new deck arch bridge and a study on its mechanical properties by FE and experiment methods

In this study, a new type of deck arch bridge was proposed based on the triangle stability principle, and its mechanical properties were tested. The new deck arch bridge—named the superposed truss arch bridge—consists of main arches, auxiliary arches, a girder, and web members. These components adopt steel structures and are connected into a series of triangles to form a superposed truss structure. The new structural system design retains the advantages of the truss and arch structure. Additionally, the rise-span ratio of the main arch can be smaller in the new system design, so the rise height is smaller, which can decrease construction difficulty. The underlying mechanical principles of the new bridge were explained. A new type of railway deck arch bridge with a 650 m span was designed, and the finite element method was used to analyze its stiffness, strength, stability, and dynamic properties and the corresponding effects of the arch-axis coefficient, rise-span ratio, and span length on the mechanical properties. An experiment was carried out on a new deck arch bridge and a conventional deck arch bridge with the same span (10 m) to compare their performance. The results showed that the new deck arch bridge exhibited good mechanical properties while being inexpensive and easy to construct, which makes it suitable for high-speed railway bridges.

Investigation on the Effect of Platform Height on Smoke Characteristics of Fire Scenarios for Subway Stations

In this study, three full-scale experiments and a series of numerical simulations were conducted to investigate the influence of subway platform height and atrium ceiling height of subway stations on smoke control by mechanical exhausting systems. The smoke temperature variation with time, maximum temperature distribution, and smoke stratification were discussed. Results showed that the atrium had capacity to store smoke, especially at the early stage of smoke spread. However, the efficiency of smoke extraction did not increase simply with the rise in platform height and atrium ceiling height, and favorable smoke exhaust velocity was crucial for smoke elimination. The optimal smoke exhaust velocity was studied by numerical simulation and it was found that the area of smoke diffusion in subway stations with a higher platform was significantly smaller under the optimal smoke exhaust velocity. In addition, a prediction model of optimal smoke exhaust velocity with subway platform height was proposed. This study could provide on-site data and smoke spread characteristics for smoke control design, operation, and, significantly, guide safety evacuation of the exhaust system of subway stations.

Simulating the Transport and Dispersal of Volcanic Ash Clouds With Initial Conditions Created by a 3D Plume Model

Volcanic ash transport and dispersion (VATD) models simulate atmospheric transport of ash from a volcanic source represented by parameterized concentration of ash with height. Most VATD models represent the volcanic plume source as a simple line with a parameterized ash emission rate as a function of height, constrained only by a total mass eruption rate (MER) for a given total rise height. However, the actual vertical ash distribution in volcanic plumes varies from case to case, having complex dependencies on eruption source parameters, such as grain size, speed at the vent, vent size, buoyancy flux, and atmospheric conditions. We present here for the first time the use of a three-dimensional (3D) plume model based on conservation laws to represent the ash cloud source without any prior assumption or simplification regarding plume geometry. By eliminating assumed behavior associated with a parameterized plume geometry, the predictive skill of VATD simulations is improved. We use our recently developed volcanic plume model based on a 3D smoothed-particle hydrodynamic Lagrangian method and couple the output to a standard Lagrangian VATD model. We apply the coupled model to the Pinatubo eruption in 1991 to illustrate the effectiveness of the approach. Our investigation reveals that initial particle distribution in the vertical direction, including within the umbrella cloud, has more impact on the long-range transport of ash clouds than does the horizontal distribution. Comparison with satellite data indicates that the 3D model-based distribution of ash particles through the depth of the volcanic umbrella cloud, which is much lower than the observed maximum plume height, produces improved long-range VATD simulations. We thus show that initial conditions have a significant impact on VATD, and it is possible to obtain a better estimate of initial conditions for VATD simulations with deterministic, 3D forward modeling of the volcanic plume. Such modeling may therefore provide a path to better forecasts lessening the need for user intervention, or attempts to observe details of an eruption that are beyond the resolution of any potential satellite or ground-based technique, or a posteriori creating a history of ash emission height via inversion.

Modelling the co-firing of coal and biomass in a 10 kWth oxy-fuel fluidized bed

The oxy-fuel co-firing of solid fuels (such as coal, biomass, and solid waste) in fluidized beds is one of the most promising technologies for the industrial application of CO2 capture and waste disposal. However, both the practical experimentation and numerical simulations for elucidating co-firing in an oxy-fuel fluidized bed are still limited. In this study, a multiphase particle-in-cell scheme based on a 3D Eulerian–Lagrangian model was further developed following our previous research on oxy-fuel co-firing in a micro fluidized bed (Powder Technol. 2020, 373, 522–534). The refined JL 4-step mechanism for the CO-CO2 homogeneous reactions, the heterogeneous reactions of char oxidation and gasification, the heterogeneous reactions of NO and N2O formation from char-N, and the self-desulfurization effect were comprehensively considered. The improvement of the models was verified through the continuous operation of 10 kWth oxy-fuel fluidized bed tests (Fuel 2021,286,119,312; Energy Fuels, 2020, 34, 7373–7387), and the effects of the biomass blending ratio (Mb) on co-firing characteristics were discussed. It was found that the improvements could enhance the adaptability of the models to the oxy-fuel atmosphere, and the accurate prediction of NO, N2O, SO2. With an increase in Mb, the main reaction zone expanded or moved up along the riser height, and the volume of the high-temperature area increased, which promoted the burnout of particles and CO2 emission when Mb is 50%. The high volatility of biomass increased O2 consumption and CO concentration at the upper part of the riser, reduced N2O formation, and had a significant impact on NO reduction. The low sulfur content and high Ca/S ratio of the biomass considerably reduced the SO2 concentration. The simulation results also provided helpful information for the design and operation control of oxy-fuel co-firing of coal and biomass in a fluidized bed, such as the oxidant supply in different areas and grades, appropriate increase in the riser height, and reasonable adoption of Mb.

Analysis of Inundation area as an Impact of Sea Level Rise in Kota Pariaman District, West Sumatera Province

This research has conducted on February 2021 in Kota Pariaman District, Sumatera Barat Province. The intention of this research was to found out the sea level rise rate based on tidal data analysis from 2001-2020 and to predict the inundation area in the 20th, 50th, and 80th to go. The method of this research was a descriptive survey by using remote sensing as the additional equipment to demonstrate the outcome. The acquisition needs are primary (land use and tidal data) and secondary (slope, elevation, land use, and tidal data) data. Those parameters were processed and analyzed to describe the area of inundation by displaying a map of Kota Pariaman. Kota Pariaman territorial water has 0,44 of Formzhal number which means the waters area is classified to mixed semidiurnal tides with the sea level rise value reach out to 2,006 cm/year. Then, the number used to predict the height of sea-level rise in 20th, 50th, and 80th to go, for each is 0,471 m; 1,073 m; and 1,675m. Furthermore, the sea level rise height was analyzed to get the inundation area in 20th, 50th, and 80th to go, turns out the flooded area for each year respectively to 14,56 ha; 23,61 ha, and 38,16 ha.

Using a stair horizontal-vertical illusion to increase foot clearance over an inconsistently taller stair-riser.

IntroductionStair falls can be caused by inconsistent stair dimensions. During ascent, inconsistently taller stair risers lead to reduced foot clearances as the inconsistency goes unnoticed. A stair horizontal-vertical illusion increases perceived riser heights and foot clearance and could offset reduced foot clearances over inconsistently taller risers, though this might impact other stair safety measures.MethodTwelve participants (age: 22 (3) years) ascended a seven-step staircase under three conditions: i) all steps consistent in riser height (consistent), ii) a 1cm increase in step 5 riser height (inconsistent) and iii) a 1cm increase in step 5 riser height, superimposed with a stair horizontal-vertical illusion (illusion). Vertical foot clearance, foot overhang, and margins of stability were assessed over step 4, 5 and 6. Perceived riser height due to the illusion was determined through a computer perception test. A One-Way Repeated Measures ANOVA compared biomechanical variables between conditions. A One Sample t test compared perceived riser height to the true height.ResultsOver the inconsistent step 5, foot clearance reduced by 0.8cm compared to consistent. Illusion increased foot clearance by 1.1cm and decreased foot overhang by 4% compared to inconsistent. On step 4 the illusion led to more anterior instability compared to inconsistent. Illusion and inconsistent led to more mediolateral stability compared to consistent. The illusion increased perceived riser height by 12%.DiscussionFoot clearance reductions over inconsistently taller risers can be offset by a stair horizontal-vertical illusion. Additional benefits included a safer foot overhang and unaffected stability over the inconsistent riser. Changes to step 4 stability might have resulted from leaning forward to look at the step 5 illusion. The stair horizontal-vertical illusion could be a practical solution for inconsistently taller stair risers, where a rebuild is usually the only solution.

Comparison of pulp sludge compost effectivity of three different decomposers to the growth of geronggang (Cratoxylon arborescens) seedlings

Pulp residue from liquid waste processing is suitable for compost materials, except for its high CN ratio so it needs composting to reduce the CN ratio. Geronggang is a native peat swamp species suitable for peat rehabilitation. The study aims to test pulp sludge compost quality enriched with three different decomposers to the growth of geronggang ( Cratoxylum arborescens ) seedlings. The sludge composting was incubated for a month using three species of decomposers, i.e., Phanerochaete chrysosporium (C); Penicillium citrinum and Penicillium oxalicum (CO); P. chrysosporium, P. citrinum and P. oxalicum (CCO). The compost is weighed and placed around the seedling's roots area with varies dosages equal to 2, 4, 6, 8, 10, 12, 14, and 16 ton ha -1 . The height and diameter of the seedlings were recorded for six months. Data was examined using ANOVA followed with DMRT at a 5% significance. The sludge compost in this study has CN ratio, Total N (%), P 2 O 5 (%) and K 2 O (%) about 40.22-44.5; 1.04-1.11; 1.05-1.13; 1.05-1.13, respectively. Statistically, the height increment of seedlings after the sludge compost application enriched with the CO was different from the CCO. However, the seedling's height rise was not statistically different at the dosages variation treatment. The raise of seedlings diameter after CO treatment at a dosage equal to 6 and 12 ton ha -1 was significantly different to the CCO at a dosage equal to 12 ton ha -1 . However, the rise of seedling's diameter was not significantly different at decomposers' variation treatment. The future study can be aimed to gain compost that meets the national standard.

Capillary-Driven Rise of Well-Wetting Liquid on the Outer Surface of Cylindrical Nozzles.

Well-wetting liquids exiting small-diameter nozzles in the dripping regime can partially rise up along the outer nozzle surfaces. This is problematic for fuel injectors and other devices such as direct-contact heat and mass exchangers that incorporate arrays of nozzles to distribute liquids. We report our experimental and numerical study of the rising phenomenon for wide ranges of parameters. Our study shows that the interplay of three dimensionless numbers (the Bond number, the Weber number, and the Ohnesorge number) governs the capillary-driven rise dynamics. In general, as the flow rate or the viscosity increases, the capillary-driven rise height over each dripping period becomes smaller. We identify liquid flow rates below which the temporal evolution of the meniscus positions can be well approximated by a quasistatic model based on the Young-Laplace equation. Our analysis reveals two critical Bond numbers that give nozzle sizes, which correspond to the maximum meniscus rise and the onset of capillary-driven rise cessation. These critical Bond numbers are characterized as a function of the contact angle, regardless of the fluid type. Our study leads to a more efficient and optimized nozzle design in systems using wetting liquids by reducing both the risks of contamination and high pressure drop in such devices.
