Microwave heating for sustainable valorization of almond hull towards high-added-value chemicals

Microwave (MW) treatment promotes homogeneous heating compared to conventional methods, thus increasing the recovery of high-added-value compounds and leading to a considerably lower amount of both by-products and side reactions. Therefore, the main goal of this work is to valorize almond hull (AH) via microwave (MW)-assisted radiation (0–200 W, 0–300 psi, 100–190 °C, 10–40 min). In this context, two different pathways were evaluated. Firstly, the transformation of AH into levulinic acid (LA), one of the major bio-based chemicals obtained from lignocellulosic biomass. The so-called almond hull extractives-free biomass (AH-EFB) led to the best results after using both Lewis (AlCl 3 ⋅6 H 2 O, 1 mol/L, 87 % molar yield) and Brønsted ( p -toluenesulfonic ( p -TsOH), 0.25 mol/L, 91 % molar yield) acids, at 190 °C for 20 min. This latter not only provides a sustainable system in contrast to mineral acids such as H 2 SO 4 or HCl, but also the possibility of being recovered and recycled for further transformations. In a parallel secondary experiment, the recovery of biologically active compounds (BACs) was studied separately. For this purpose, antioxidant assays and phenolic profiling were carried out, which demonstrated that MW was more efficient than traditional methods (i.e. soaking) based on obtained values in terms of scavenging activity and polyphenols. Overall, this valorization approach involves most of the Green Chemistry principles, thus contributing to the development of almond biorefineries. • Bioenergy and biofuels can be obtained from almond by-products. • Almond hull can provide high-added-value chemicals. • MW treatment increased the extraction of polyphenols and antioxidant activity.

Microwave-assisted Synthesis of Fluorinated Heterocycles

Abstract: The diverse biological applications of fluorinated heterocycles make them crucial chemical compounds. Several synthetic processes have been developed for their synthesis. Microwave-assisted synthesis has emerged as an important technique for generating fluorinated heterocycles in an eco-friendly and energy-efficient manner. It provides several benefits like less reaction time, high reaction yield, homogeneous heat distribution leading to lower side reaction, and better control of reaction temperature. Recently there has been significant progress in microwave use for heterocycle synthesis. This article discusses the applications of microwave irradiation in the synthesis of oxygen- and nitrogen-containing fluorinated heterocycles.

Effect of Butt Gap on Stress Distribution and Carrying Capacity of X80 Pipeline Girth Weld.

An unstable assembly gap is detrimental to the formation and performance of the pipeline butt girth weld joint. Therefore, a numerical model of an 18.4 mm-thick X80 pipeline girth weld by a homogeneous body heat source was established to investigate the effect of the butt gap on the joint temperature and stress field, and carrying capacity. The accuracy of the simulation results was verified by measuring the welding thermal cycle with a thermocouple. The investigation results showed that the weld pool, heat-affected zone (HAZ) width, and maximum circumferential stress of the joint rose with the increase in the butt gap. The tensile stress unfavorable to the joint quality was mainly distributed in the weld metal and partial HAZ, and the distribution areas gradually expanded as the gap increased. The Von Mises stress peak value of the joint appeared in the order of 3 mm > 2 mm > 1 mm > 0 mm gap, reaching the maximum of 467.3 MPa (3 mm gap). This variation trend is directly related to the improvement in welding heat input with increasing butt gaps. The maximum Von Mises stress of the joint was positively correlated with the carrying capacity of the pipeline, which diminished as the butt gap enlarged. The pipeline carrying capacity reached 17.8 MPa for the joint with no butt gap, and dropped to 13.1 MPa for the joint with a 3 mm gap. The relationship between the carrying capacity (P) and butt gap (C) was described by P = −0.125C2 − 1.135C + 17.715, through which the pipeline carrying capacity with other butt gaps can be predicted.

Spatially resolved spectroscopy of alkali metal vapour diffusing inside hollow-core photonic crystal fibres

We present a new type of compact and all-glass based vapour cell integrating hollow-core photonic crystal fibres. The absence of metals, as in a traditional vacuum chamber and the much more compact geometry allows for fast and homogeneous heating. As a consequence we can fill the fibres on much faster timescales, ranging from minutes to hours. Additionally the all-glass design ensures optical access along the fibre. This allows live monitoring of the diffusion of rubidium atoms inside the hollow-core by measuring the frequency-dependent fluorescence from the atoms. The atomic density is numerically retrieved using a five-level system of Bloch-equations.

Microwave sintering of dense and lattice 3Y-TZP samples shaped by digital light processing

Nowadays it is possible to produce ceramic parts with solid and complex shapes with rapid and efficient shaping and sintering techniques. In this paper, 3mol% yttria stabilized zirconia (3Y-TZP) dense and lattice parts were shaped by Digital light processing method (DLP) and densified by conventional (CV) and microwave (MW) sintering. 3Y-TZP samples were MW sintered up to 1550 °C with different heating rates (10, 30, and 50 °C/min) for the dense samples and 30 °C/min for the lattice samples. Controlled thermal cycles with a homogenous heating and no thermal runaway was reached. CV sintering was carried out at 10 °C/min up to 1550 °C. No inter-layer delamination was detected after sintering by the two methods. Both dense and lattice MW-sintered samples reached high final densities (equivalent to obtained values with CV-sintered samples, i.e. , ≥98% T.D.), but exhibited a lower average grain size than CV-sintered materials. The different architectures between dense and lattice samples resulted in a different specific absorbed power: the power absorbed by the dense sample is lower than that absorbed by the lattice one meaning that this sample architecture heats up easily.

Heterostructure composites of TiO2 and CdZnS nanoparticles decorated on Ti3C2Tx nanosheets and their enhanced photocatalytic performance by microwave hydrothermal method

Single transition metal oxide photocatalysts face the problems about low utilization of sunlight and easy recombination of photogenerated carries. In this paper, TiO2 @Ti3C2/CdxZn1−xS (MT-xC) composite photocatalysts were prepared in one step with the aid of microwave hydrothermal method by synergistic in situ compounding and construction of semiconductor heterojunction. The results showed that when the microwave hydrothermal temperature was 140 °C, the reaction time was 0.5 h and the CdZnS loading was 30 wt%, MT-3 C photocatalyst demonstrated good photocatalytic performance, with a degradation efficiency of 93.66% for 20 mg/L rhodamine B (RhB) within 90 min. The main reason for this significant improvement is that TiO2 and CdxZn1−xS have matched band structure, the spatial separation of photogenerated carries in photocatalytic reactions can be accelerated by constructing a Z-type heterojunction. Moreover, the efficient and homogeneous heating of microwaves can provide a large amount of energy for the oxidation of Ti3C2 within a short time. The synergistic effect of semiconductor heterojunction composed of Ti3C2, TiO2 and CdxZn1−xS and microwave can further improve the catalytic activity of the composite photocatalyst.

Clarifying the phenomenon of Ultrasonic Assisted Electric discharge machining

In this research work, an attempt was made to machine the Nimonic alloy utilizing the Ultrasonic Vibration assisted Electric Discharge Machining (UVEDM) Process and performance was accessed in terms of material removal rate, tool wear rate and surface roughness. The key finding includes, increase in MRR was achieved by the complete flushing of machined debris and the generation of an intensified plasma channel, while the decrease in R a was induced by uniform heat distribution. With UVEDM, machined performance was improved due to the fact that UV facilitates the homogeneous heat distribution, which was corroborated by analyzing the surface topography of machined debris. Globules, pock marks, cracks, pits, material doom and craters were the distinct features observed on the surface topography. The shape of the machined debris was angular, erroneous circular, spherical and irregular for the UV frequency of 0,20,40 and 60 kHz respectively. The process parameters utilized for study was optimized using the MOORA-ELECTRE Integrated Optimization Technique (MEIOT). • Ultrasonic Assisted Electric discharge machining was performed to improve the machinability. • The impact of UV over the machining was analysis by characterizing the machined debris. • With UV, generated heat distributs evenly throughout machined surface, results in clean surface and reliable spark discharge. • The optimized process parameters was identified using the MEIOT technique.

Ink-Deposited Transparent Electrochromic Structural Colored Foils.

Despite progress in the field of electrochromic devices, developing structural color-tunable photonic systems having both high transparency and flexibility remains challenging. Here, an ink-deposited transparent electrochromic structural colored foil displaying reflective colors, tuned by an integrated heater, is prepared in a single-substrate method. Efficient and homogeneous heating is induced by a gravure printed silver nanowire-based substrate, delivering an electrothermal response upon applying an electrical potential. On top of this flexible, transparent heater, a cholesteric liquid crystal ink is bar-coated and subsequently photopolymerized, yielding a structural colored film that exhibits temperature-responsive color changes. The transparent electrochromic foils appear colorless at room temperature but demonstrate structural color tuning with high optical quality when modifying the electrical potential. Both optical and electrothermal performances were preserved when deforming the foils. Applying the conductive and structural colored inks via the easy processable, continuous methods of gravure printing and bar-coating highlights the potential for scaling up to large-scale stimuli-responsive, transparent optical foils. These transparent structural colored foils can be potentially used for a wide range of photonic devices including smart windows, displays, and sensors and can be directly installed on top of curved, flexible surfaces.

Abundances of Uranium and Thorium Elements in Earth Estimated by Geoneutrino Spectroscopy

AbstractThe decay of the primordial isotopes 238U, 235U, 232Th, and 40K has contributed to the terrestrial heat budget throughout the Earth's history. Hence, the individual abundance of those isotopes are key parameters in reconstructing contemporary Earth models. The geoneutrinos produced by the radioactive decays of uranium and thorium have been observed with the Kamioka Liquid‐Scintillator Antineutrino Detector (KamLAND). Those measurements have been improved with more than 18‐year observation time, and improvement in detector background levels mainly with an 8‐year nearly reactor‐free period, which now permit spectroscopy with geoneutrinos. Our results yield the first constraint on both uranium and thorium heat contributions. The KamLAND result is consistent with geochemical estimations based on elemental abundances of chondritic meteorites and mantle peridotites. The High‐Q model is disfavored at 99.76% C.L. and a fully radiogenic model is excluded at 5.2σ assuming a homogeneous heat producing element distribution in the mantle.

Viscosity of Earth’s inner core constrained by Fe–Ni interdiffusion in Fe–Si alloy in an internal-resistive-heated diamond anvil cell

Abstract Diffusivity in iron (Fe) alloys at high pressures and temperatures imposes constraints on the transport properties of the inner core, such as viscosity. Because silicon (Si) is among the most likely candidates for light elements in the inner core, the presence of Si must be considered when studying diffusivity in the Earth’s inner core. In this study, we conducted diffusion experiments under pressures up to about 50 GPa using an internal-resistive-heated diamond-anvil cell (DAC) that ensures stable and homogeneous heating compared with a conventional laser-heated DAC and thus allows us to conduct more reliable diffusion experiments under high pressure. We determined the coefficients of Fe–nickel (Ni) interdiffusion in the Fe–Si 2 wt% alloy. The obtained diffusion coefficients follow a homologous temperature relationship derived from previous studies without considering Si. This indicates that the effect of Si on Fe–Ni interdiffusion is not significant. The upper limit of the viscosity of the inner core inferred from our results is low, indicating that the Lorentz force is a plausible mechanism to deform the inner core.

CFD simulation of conjugated heat transfer with full boiling in OpenFOAM(R)

The Computational Fluid Dynamics (CFD) simulation of subcooled and saturated boiling flow with multi-domain thermal coupling is a challenge, and the current methods to solve the exchange of mass, momentum, and energy still require further development and validation. This work addresses the implementation and assessment of a new solver (CHT-2FM) in OpenFOAM(R), which includes the Conjugated Heat Transfer (CHT) model into the two-phase Eulerian method (2FM) in order to solve wall boiling. This solver allows applying the wall heat flux partitioning model (Rensselaer Polytechnic Institute) to solve subcooled and saturated boiling flows coupling two fluid circuits through a solid domain, without impose the heat flux at the heater wall. The solver is experimentally and numerically validated against three tests; First the well-known vertical heated pipe with homogeneous heat flux proposed by Bartolomej et al. (1982) was solved to assess the RPI model, and the interfacial momentum exchange. The test was also solved with RELAPMod3 in order to assess the boiling model implemented in this code. Second, a numerical low-pressure benchmark of a vertical double-pipe evaporator proposed by Abishek et al. (2017) was solved. This allow comparing some RPI model parameters, and the CHT implementation. The third test was proposed by the authors in order to evaluate the CHT-2FM implementation for water operation conditions relevant for nuclear engineering. The test was also solved with RELAPMod3. Based on the first test, the RPI model in OpenFOAM correctly solved the Bartolomej test in terms of void fraction. On the contrary, RELAPMod3 overestimated boiling at the end of the pipe. From the second test it was concluded that the CHT-2FM coupling was correctly implemented. Finally, the use of the developed tool to solve heat coupled fluid systems led to very acceptable solutions compared with RELAPMod3 estimations.

Thermal Operational Map of an ESP-In-Skid Motor: A CFD Approach

The production of oil in offshore wells has used artificial lifting methods in order to maintain or increase production. In this sense, several established methods for onshore production, such as electrical submersible pumping (ESP), have been implemented in offshore scenarios and, as a consequence, new challenges and needing improvements to optimize production in this type of environment had to be faced. Many studies concern the gas-liquid flow inside de pump but avoid include the motor and its thermal management. In this context, this study focused to assess the complex flow around an ESP motor installed in subsea skids on the seabed (Skid-ESP) through the analysis of their operational and geometric conditions using a computational fluid dynamics (CFD) tool. The main question is: is it possible to create a thermal operational map of the motor in function of motor frequency with CFD tools? The Volume-of-Fluid (VOF) model was applied together with a homogeneous heat transfer (shared temperature field among phases) coupled to the heat conduction inside motor. This approach is known as Conjugate Heat Transfer (CHT). The ESP motor is modeled as a homogeneous and isotropic body with constant volumetric heat generation. The flow analysis was performed applying the model on an industrial scale with incompressible oil and gas in in-situ conditions and considering the heat transfer between the fluid mixture and the its boundary conditions (seawater constant temperature of 4°C and variable motor heat flux as function of motor frequency). The motor frequency range considered was between 40 and 60 Hz. Since the model used was 3D, hot spots were observed at the low part of near seal motor side for gas volume fraction above 3.5%. The employed methodology was able to determine the thermal operational map with a 5% average deviation from field data.

Fast, High Quality and Low-Cost Biodiesel Production using Dolomite Catalyst in an Enhanced Microwave System with Simultaneous Cooling

• It was established a Microwave-assisted biodiesel production system (EMS) that worked under constant-continuous microwave power and isothermal conditions. • Biodiesel production experiments were carried out in the EMS utilizing the "one variable at a time" method to estimate optimum values of the parameters. • Faster, higher-quality, and lower-cost biodiesel production was accomplished when compared to the conventional heating system (CHS). • Advantages of selective heating feature of microwave energy in terms of different methyl ester production were revealed. In this study, biodiesel production with canola oil and methanol in the presence of dolomite catalyst was examined in a multimode Enhanced Microwave System (EMS) with simultaneous cooling worked under constant, continuous microwave (MW) power and isothermal conditions. The experiments were carried out in the EMS utilizing the "one variable at a time" method to estimate optimum values of five experiment parameters named methanol-to-oil molar ratio (n m /n o ), amount of catalyst (% wt of oil), temperature (T,°C), reaction time (t, min) and absorbed MW power (P a, W). The optimum values of these parameters were obtained as 9, 5%, 65°C, 120 min., 48 W, respectively. At the end of the study in EMS, an experiment was repeated in the Conventional Heating System (CHS) at the optimum conditions. Accordingly, it was found that the yield of biodiesel in EMS (99.1%) during the same period was 30.2% higher than in CHS (76%). Faster, higher-quality, and lower-cost biodiesel production was accomplished when compared to the CHS. Energy and production cost saving were accomplished by 58.2 % and production rate was increased by 30.4% in EMS. Furthermore, selective and homogenous heating effect on catalyst's local surface temperature and strong vibrational effect of MW on dipoles provided advantages in terms of catalyst activity and different methyl ester content. This showed that biodiesel with different properties can be produced using same oil in the EMS.

Electrical swing adsorption on 3D-printed activated carbon monoliths for CO2 capture from biogas

• Electrically conductive 3D-printed activated carbon monolith heats up homogenously. • Very fast heating could be obtained (>150 °C in less than 30 s at 8 V). • Impact of operation parameters in ESA were assessed for biogas separation. • Process improvements were performed to enhance recovery/purity of CO 2 . Direct, resistive or Joule heating of the adsorbent allows for the intensification of Thermal Swing Adsorption processes by reducing process cycle time and reducing heat losses. In this work, an electrically conductive activated carbon monolith was 3D-printed using a potassium silicate binder. The monolith was assessed for biogas upgrading, using Joule heating for regeneration of the monolith. The electrification of the 3D-printed monolith resulted in very rapid and homogenous heating, to 150 °C in less than 30 s at a potential of 8 V. Next, the monolith was subjected to cyclic adsorption-desorption experiments for CO 2 capture from a synthetic biogas mixture (30 v% CO 2 – 70 v% CH 4 ). The main parameters in ESA, namely voltage, electrification time, purge conditions and an additional rinsing step were investigated by determining the impact on the heating, regeneration efficiency and purity. Increasing the voltage from 4 V to 8 V step is preferred for recovery (82–95%) as well as for energy consumption, as it increases the efficiency (27.1–28.4%). It was also found that using the same amount of purge gas, it is preferred to use a higher purge flow rate for a shorter time (100 Nml/min for 15 s) over a lower purge flow rate for a longer time (50 Nml/min for 30 s). This benefits both recovery (87.3% vs 84.0%) and purity (84.5% vs 83.4%). Lastly, the benefit of adding a rinse step to increase the purity was demonstrated, where having a rinse step prior to electrification allowed to augment the total purity from 58% to 81.2%, while the regeneration of the monolith was as efficient.

Analysis of natural convection flows of Jeffrey fluid with Prabhakar-like thermal transport

The free convection flow of Prabhakar fractional Jeffrey fluid on an oscillated vertical plate with homogenous heat flux is investigated. With the help of the Laplace transform and the Boussinesq's approximation, precise solutions for dimensionless momentum may be found. The temperature and velocity of Prabhakar fractional time free convection flows are compared to conventional thermal transport, as shown by Fourier's law. They met all of the requirements and recovered Newtonian and ordinary Jeffrey fluid solutions from fractional Jeffrey fluid. Finally, graphs show the effect of various physical parameters such as fractional parameters, Grashof number, Prandtl number and Jeffrey parameters on both temperature and velocity.

ЕКСПЕРИМЕНТАЛЬНІ ДОСЛІДЖЕННЯ ТЕПЛОПРОВІДНОСТІ ТЕПЛОІЗОЛЯЦІЙНИХ МАТЕРІАЛІВ ІЗ МІНЕРАЛЬНОЇ ВАТИ

According to the analysis of domestic and foreign literature sources, it is noted that reducing energy consumption to create an optimal microclimate of buildings involves reducing heat loss through external enclosing structures. Construction of new buildings and thermal modernization of existing ones is carried out with the use of different properties of thermal insulation materials, passport data of manufacturers on their characteristics need to be clarified in determining the energy efficiency of buildings. Mineral wool was selected for experimental studies of thermal insulation material used to improve the thermal insulation shell. The energy efficiency of mineral wool was studied using an installation with a climate chamber with a homogeneous heat flux over the cross-sectional area of ​​the sample. To register the change in the amount of heat flux, thermocouples were used, which are located at different points of the climate chamber with a sample of mineral wool. Data on the change in temperature during the observation period before the stabilization of the heat flux was determined by the automatic registration unit. The change in time of the temperature regime at different points of the mineral wool sample is obtained. The thermal conductivity, which characterizes the efficiency of the thermal insulation material made of mineral wool, was calculated according to the known Fourier formula for stationary thermal regime from the values ​​of the temperature difference in the characteristic cross sections of the sample. The discrepancy between the values ​​of thermal conductivity of the investigated sample and the passport data of thermal conductivity of mineral wool provided by its manufacturer is revealed.

A new biaxial apparatus for tensile tests on Poly Ethylene Terephthalate optimized specimen at stretch blow molding conditions

Characterization of polymer behavior over or near the glass transition temperature in condition close to industrial process remains a scientific goal. In particular being able to manage multiaxial loading at high strain rate and large strains is particularly interesting to understand Poly Ethylene Terephthalate (PET for short) behavior at condition near to the blowing process. In this paper, we present a new vertical biaxial tensile machine that has been designed and built up in our laboratory. In particular, (i) thermal regulation enables a fast and homogeneous heating of the specimen at temperature close to Tg, (ii) strain rate up to 5s−1 can be reached and (iii) a cruciform specimen geometry has been optimized to ensure large biaxial strain up to 2 or more in each direction. These two last are lower but close to the strain rate and elongation observed in stretch blow molding. The digital image correlation technique is used to obtain the displacement field and a thermal camera gives the evolution of the temperature field during the test. Dimension and height enables this apparatus to be transportable for mechanical tests under SAXS or WAXS. Here we present results of tests managed on PET and the identification procedure that is carried out to fit parameters of our orthotropic thermo-visco-hyperelastic model. Results are presented, discussed and compared to previous measures obtained from apparatus that are more complex.

A meta-analysis of thermo-physical and chemical aspects in CFD modelling of pyrolysis of a single wood particle in the thermally thick regime

• Anisotropy is required to model gas velocities in single particle pyrolysis correctly. • The heat sink drying model is generally recommended for moist wood. • The Ranzi-Anca-Couce kinetic scheme shows higher accuracy than the Ranzi scheme. • The developed model has a good accuracy within the broad range of parameters. • Particles smaller than 4 mm can achieve a high heating rate over the whole volume. Thermochemical conversion of larger biomass particles (thermally thick regime) toward high-end products still suffers from an unrevealed quantitative relationship between process and product parameters. The main issue relates to the influence of heating rate within the particle, critical conversion-wise but difficult to assess experimentally. Computational fluid dynamics (CFD) modelling may help, but first the model must prove its reliability to prevent error transfer to the results. This study aimed to provide an unbiased, state-of-the-art model constructed in a stepwise mode to investigate the heating rate’s distribution. Several datasets with broadly varying parameters from the literature were used for the development and validation since the reproduction of datasets would not bring novelty to solving the problem. Instead of the model’s calibration to fit to the data, the parameters for each step-model were meticulously selected to match the experimental conditions. The stepwise development showed the best accuracy when the anisotropy and the heat sink drying sub-model were implemented. Moreover, using the Ranzi-Anca-Couce (RAC) scheme led to more accurate results than the Ranzi scheme. The comprehensive model was positively validated against a broad range of production parameters (pyrolysis temperature: 500 °C − 840 °C, diameter of particles: 10 mm − 20 mm, shapes: cylinders and spheres). Investigation showed a pattern in volatiles release profiles and homogeneous heating rate distribution when particle size is below 4 mm. Despite basing the models on the literature’s data, the study includes novel and valuable insights for biomass conversion and constitutes a solid foundation for future development.

The The Production of Roasted Peanuts Using the Semi-Mechanical Roaster in Keranggan Village

Roasted peanuts typically have a unique taste with a distinctive roasted aroma and a savory flavor different from peanuts processed using an oven. To make roasted peanuts, two critical stages should be observed: the sanitation during washing and the roasting technology. The current study focuses on the application of roasting technology in the production of roasted peanuts among the households in Keranggan Village, Setu District, South Tangerang City. It was an issue that the household scale manufacturing of roasted peanuts there did not meet the standard process, relying on manpower to monitor when the roasting process should end even though fatigued workers may produce burnt peanuts up to 19%. Therefore, to reduce the percentage of burnt peanuts, a semi-mechanical roasted fryer was developed for the roasted peanut entrepreneurs in Keranggan Village, Setu District, South Tangerang City. The research team conducted socialization of effective roasting technology, provided assistance, and delivered the semi-mechanical roasters to the community. The team also performed a direct test on the semi-mechanical roaster at both the Indonesian Institute of Technology laboratory and Keranggan Village, in addition to providing assistance on how to use the tool. The semi-mechanical roaster itself is made of stainless steel with a diameter of 100 cm, equipped with a stirrer powered by an electric motor capable of roasting automatically within a certain time limit. This will produce a homogeneous heat transfer with the sand media, which is not changed in line with the original roasting method. The lab and field trials showed that the burnt yield decreased to 5%. Furthermore, when compared to those produced through manual roasting, the sensory test of the products, showed results that were not significantly different even with a sensory value of appearance (i.e., the color) higher than that of manual roasting.

Flower Shaped Oscillating Heat Pipe at the thermosyphon condition: Performance at different rotational speeds, filling ratios, and heat supplies

The performance of a very effective and innovative thermal device based on Pulsating Heat Pipes (PHP) in a rotating system is studied and analysed in the paper. The appliance called a Flower Shaped Oscillating Heat Pipe (FSOHP) is developed for use in industrial sectors and is arranged in the specific shape of a flower so as to obtain homogeneous heat reception from technological processes. The capillaries, with an inner diameter of 2.7 mm, were filled and tested, with HFE−7000 as a working fluid. This fluid, according to a confinement criterion based on the Bond or Garimella numbers, places the device in the range of thermosyphon operation, the description and experimental verification of which is addressed in this paper. The influence of rotational speed (0–300 rpm), heat input (300–450 W), and filling ratio (40–90%) on the thermal performance has been studied as an experimental research. Current research shows that a low boiling point liquid such as HFE−7000 can be used as a working fluid in a rotating system, and the thermal resistance of the process is characterised by a value of almost 100% higher compared to water. The maximum value of the heat flux value achieved was equal to 22.1 kW/m2 for HFE−7000, while for water it was more than four times higher and equal to 98.4 kW/m2. It was also observed that by increasing the Filling Ratio (FR) by up to 80%, the thermal resistance decreases to the lowest value of 0.05 K/W in speed conditions such as above 200 rpm. Results have shown that with respect to dimensionless numbers, despite going beyond the scope of the confinement criterion, FSOHP achieves a low value of thermal resistance and temperature stabilisation with characteristics very similar to those that describe standard pulsating heat pipe solutions in a stationary system. Furthermore, in a rotating system, an increase in heating power improves the thermal efficiency of the device only for FR >70%, while in a stationary system, an increase in the power supply range studied is always associated with a decrease in thermal resistance, regardless of the FR.
