Computational comparison and experimental performance analysis on heat pipes using concentrating solar parabolic trough collector

The heat pipes in solar applications uses are important and it is significantly growing nowadays. Capable of meeting the world’s challenges with a threat to the climate; a shortage of conventional energy sources, usually fossil fuels, high electricity costs, and it is inexpensive; therefore, the renewable energy of solar energy is an excellent source, reaching total amount of energy is 34,00,000 EJ in each year, all over the world. This is between 7000 and 8000 times the annual global primary energy consumption. Thereby, a Concentrating Solar Parabolic Trough Collector is suggested in this paper, which can be used to analyze the performance of various heat pipes. Using solar parabolic trough collector to analyze the performance of different heat pipes rather than considering the supply of electric power input. Using a parabolic trough collector that concentrates solar energy on an evacuated tube heat pipe, which converts radiation energy into electrical energy heat, the experimental work demonstrates the use of solar energy. Condensers, evaporators, and three heat pipes consisting of aluminum galvanized iron, and stainless steel materials are the main components. A porous wick structure and an ammonia solution-filled working fluid consist of each heat pipe. Continuously recirculating the working fluid through temperature variation. The readings are taken using connected thermocouples on three heat pipes by continuously varying the mass flow rate. The vacuum pressure gauge to maintain the heat pipes generates the vacuum inside space. At various mass flow rates of heated water from the parabolic trough collector, experimentation was also performed. The result of this study calculates the mass flow rate at the end of the process of the different heat pipes used here. Furthermore, different inclinations are estimated in a variety of situations, such as at temperatures of 15°, 30°, 45°, and 60°. In the experimental analysis, outlet temperatures of heat pipes are measured and the temperature distribution contours are evaluated using the analysis of computational fluid dynamics.

Ionic heat dissipation in solid-state pores.

Energy dissipation in solid-state nanopores is an important issue for their use as a sensor for detecting and analyzing individual objects in electrolyte solution by ionic current measurements. Here, we report on evaluations of heating via diffusive ion transport in the nanoscale conduits using thermocouple-embedded SiNx pores. We found a linear rise in the nanopore temperature with the input electrical power suggestive of steady-state ionic heat dissipation in the confined nanospace. Meanwhile, the heating efficiency was elucidated to become higher in a smaller pore due to a rapid decrease in the through-water thermal conduction for cooling the fluidic channel. The scaling law suggested nonnegligible influence of the heating to raise the temperature of single-nanometer two-dimensional nanopores by a few kelvins under the standard cross-membrane voltage and ionic strength conditions. The present findings may be useful in advancing our understanding of ion and mass transport phenomena in nanopores.

A Fully Self‐Powered Cholesteric Smart Window Actuated by Droplet‐Based Electricity Generator

AbstractSelf‐powered smart windows are highly attractive for the development of energy‐efficient buildings system, owing to their superior capacities in regulating the energy and information exchange between indoor and outdoor environments. Although immense achievement has been made in the self‐powered cholesteric liquid crystal smart window (CLC‐SW) based on triboelectric nanogenerators (TENGs), such a self‐powered manner is limited by some challenges such as the need of the continuous input of external forces, as well as unstable performance owing to inevitable mechanical abrasion of TENGs surface. Here, a fully self‐powered CLC‐SW is developed by leveraging droplet‐based electricity generator (DEG) as a spontaneous and sustained energy reservoir, in which DEG has superior capacities to harvest ceaseless energy from ambient environment and circumvent any additional electrical power input. It is demonstrated that DEG‐driven CLC‐SW exhibits a rapid response and high tunability in the transformation between the transparent state and the hazy state in a wide range of solar spectrum. Moreover, both the transparent and hazy modes can be self‐sustained for a long time, also be reversibly switched by the gentle mechanical pressure loading. The DEG‐driven smart window developed in this work can find applications such as indoor temperature modulation and privacy information protection.

Steam methane reforming driven by the Joule heating

The main objective of this work is to present a new particle unresolved 3D-1D DEM-CFD-based model enabling predictions of a new steam methane reforming (SMR) driven by the direct electrical current. The main feature of this technology is the use of metal particles heated by the Joule heat resulting from direct electrical current flowing through metal particles in order to heat the gas phase and catalyst particles (Ni/α-Al2O) to sustain endothermic chemical reactions. The model uses six gaseous chemical species (CH4, CO2, CO, H2O, H2, N2) in the gas phase inside the catalyst. The Langmuir–Hinshelwood-Hougen-Watson (LHHW) kinetics is used. The distinguishing feature and the novelty of the model presented in this work consist in the calculation of the 3D distribution of the electric field inside non mono-disperse fixed beds. The electric field distribution is used to calculate the Joule heating term for each electrically conducting particle participating in the electrical current flow. Additionally, the new model predictions are compared with alternative models based on the chemical equilibrium principles. The models have been numerically solved using MATLAB. To illustrate the performance of the models and to check the feasibility of a new electrical steam methane reforming concept, we consider a cylindrical electrically insulated tube with a diameter of 0.1 m and a height of 0.5 m, which is filled with metal particles and catalyst particles with diameters of 5 mm and 2 mm, respectively. Parametric runs for different flow rates from 0.0025 kg/s to 0.01 kg/s and electrical power from 6.9 kW to 39 kW have been carried out. Results of simulations showed that an increase in the flow rate value (ṁ) by keeping constant input electrical power leads to a decrease in the conversion of CH4 proportionally to ṁ-1/2. A linear increase in the flow rate and input power leads to a decrease in methane conversion. When the input electrical power is increased, the difference between catalyst particle temperature and gas temperature decreases.

Modeling of SCIG-Based Variable Speed Wind Turbine in Power Factor Control Mode for Load Flow Analysis

As they are more efficient in extracting wind energy, variable speed wind power plants (WPPs) are currently replacing the fixed speed WPPs. One possible way to achieve a variable speed WPP is by using a squirrel cage induction generator (SCIG) with full-scale power electronic converter (PEC). In fact, as its cost is relatively lower, the application of SCIG-based variable speed WPP is gaining popularity nowadays. To be able to perform proper analyses (including the load flow analysis) of an electric power system, valid and accurate modeling of the system components is very important. This paper discusses the steady state model of SCIG-based variable speed WPP in power factor control mode for a load flow analysis of an electric power distribution system. The model was developed based on formulas that calculate the turbine mechanical power input and WPP electrical power output. Integration of the proposed model in load flow analysis is also discussed and presented in this paper.

Fabrication and Cooling Performance Optimization of Stretchable Thermoelectric Cooling Device

Stretchable electronic devices are known as elastic electronics or circuits. They are typically built by deposition or embedding of devices and circuits onto stretchable substrates, which can sustain large strains without failure. The research on this emerging technology has focused on the development of components based on insulators, conductors, or semiconductors to overcome inherent difficulties of generating mechanically stable layers and interconnections. In addition to the mechanical challenges, the heat-dissipation problem, remains yet to be solved, since stretchable electronics are generally fabricated using materials with poor thermal conductivities. To simultaneously address stretchability and heat dissipation, novel cooling platforms are required. As one promising pathway, this paper presents the fabrication and performance optimization of a thermoelectric device that is stretchable and effectively dissipates heat. The device is easy to fabricate and has a relatively simple structure, consisting of a silicone elastomer (Ecoflex), liquid metal, and thermoelectric legs. It is mechanically stable over 1000 stretching-and-releasing cycles with 30% strain. A thermal analysis reveals that the Ecoflex substrates impose significant thermal resistances to the entire device, degrading its cooling performance. To address this issue, alumina powder is added into the Ecoflex substrates. For the case of Ecoflex/alumina composite substrates with 60 wt % alumina, the maximum temperature drop is enhanced by 80 and 50% at 0 and 30% strains, respectively, under no heat load conditions. The devices with alumina addition also show a highly improved cooling per unit electrical power input, suggesting their potential merit in cost and energy saving. The cooling capability of the stretchable thermoelectric devices is further confirmed under both conductive and convective heat load conditions.

Improvement mechanism of energy conversion efficiency in ultrasonic motor with flexible rotor

Flexible rotors are widely used in traveling wave rotary ultrasonic motors (TRUMs) because of their higher energy conversion efficiency; however, there have been few reports on how flexible rotors improve the energy conversion efficiency of ultrasonic motors. In this study, we investigate the improvement mechanism of energy conversion efficiency in TRUMs with flexible rotors. A 3D finite element (FE) model with full coupling among a piezoelectric coupled stator, rotor, friction layer, and the rigid–elastic contact interface of the stator and friction layer is established. To analyze the mechanism by which the efficiency of the TRUM is improved, the contact interface and rotor vibration information are extracted. Taking TRUM-60 as an example, the transient solution method and modal analysis method are used to solve the model. It is found that when the stator mode is B09, the flexible rotor mode is B19. The energy conversion efficiency of the TRUM is obtained from the ratio of output power to the electrical input power of the model solution. The results are validated using 3D vibration measurements and energy conversion efficiency experiments. The simulation result shows that the motor with flexible rotor improves the energy conversion efficiency compared with the motor with rigid rotor, which can be attributed to two reasons: first, the axial amplitude ratio of the flexible rotor to the stator is reduced; second, the flexible rotor reduces the radial friction. This study reveals the influence of flexible rotor on the output efficiency and can thus provide guidance for rotor design.

New solutions for remote monitoring of pre-cast concrete service reservoir and sludge lagoon

The use of distributed temperature and/or strain measurements for embankment and reservoir monitoring has grown in recent years. The paper elaborates on two different methods applied through two installation examples in the UK. To reduce risk, a leakage monitoring system using distributed fibre optic temperature sensing (DTS) with a spatial resolution of 0.7 m has been installed at the newly constructed 45ML Hanchurch Service Reservoir. The gradient method provides information regarding possible seepage by monitoring absolute temperatures over time. Heat pulse method consists of measuring the temperature changes over time using DTS following heating the hybrid cable with a known electrical power input. Central to the £7 million investment on the century-old Curdworth sludge lagoon is the installation of a novel combined leakage and movement of the early detection system. The system is based on distributed fibre optic sensing methods for measuring strain and temperature, both fully automated with a time resolution of about an hour. Instrumentation can be analysed in real time. Trigger levels are being established during a trial period, linked to an automatic alarm system, which supplements site-based surveillance. This will facilitate the early detection of potential embankment/reservoir integrity issues and, in turn, will enable prompt action to be taken to reduce risk and in an extreme case the implementation of essential repairs in order to prevent a dam failure.

Fabrication of an acetone gas sensor based on Si-doped WO3 nanorods prepared by reactive magnetron co-sputtering with OAD technique

Gas sensing technology is currently applied in a variety of applications. In medical applications, gas sensors can be used for the detection of the biomarker in various diseases, metabolic disorders, diabetes mellitus, asthma, renal, liver diseases, and lung cancer. In this study, we present acetone sensing characteristics of Si-doped WO3 nanorods prepared by a DC reactive magnetron co-sputtering with an oblique-angle deposition (OAD) technique. The composition of Si-doped in WO3 has been studied by varying the electrical input power applied to the Si sputtered target. The nanorods film was constructed at the glancing angle of 85°. After deposition, the films were annealed at 400 °C for 4 h in the air. The microstructures and phases of the materials were characterized by x-ray photoelectron spectroscopy (XPS), x-ray diffraction (XRD), and field-emission scanning electron microscopy (FESEM). The results showed that 1.43 wt% Si-doped WO3 thin film exhibited the maximum response of 5.92 towards 100 ppm of acetone at performing temperature (350 °C), purifying dry air carrier. The process exposed in this work demonstrated the potential of high sensitivity acetone gas sensor at low concentration and may be used as an effective tool for diabetes non-invasive monitoring.

Antifouling with Chloride Ion Electrolytic Recycling through a Momentum Boundary Layer

AbstractSeaLite Engineering, after a 10-yr research and development program, has produced an operational antifouling system for ocean sensors and instruments designed for low power consumption and long (>1 yr) deployments. The important innovation is the replacement of pumps by gravity and external motion to significantly reduce energy consumption. Also, a prototype system for autonomous underwater vehicle control surfaces is now undergoing laboratory testing. The effectiveness of SeaLite’s technology has been demonstrated year-round in northern estuaries and in the Gulf of Mexico, the latter by an independent agency. The process leading to this result was, first starting in 2010, an extensive laboratory evaluation of electrode alloys, calibration of chlorine production versus electric power input, and the location for attaching electrodes to various objects requiring protection from fouling. After 2015 the experimentation moved to the ocean, first in a Cape Cod estuary and then to the Gulf of Mexico. Comparisons with a mechanical antifouling system were done in situ, and with a UV antifouling system from AML Oceanographic, Ltd., by comparing the data. Starting in 2019, the development of biofilms, from their initial deposition through the extra polysaccharide substance stage, were experimentally investigated by taking samples from an estuary near SeaLite’s laboratory. Biofilms on microscope slides and water column samples were collected. This was done in different seasons, from spring bloom, summer doldrums, autumn temperature decline, and the winter freeze. The objective was to determine the level of biofilm growth that would require antifouling, and its’ seasonal, temperature, and solar radiation dependence, and thus to conserve power.

A two-stage thermally-coupled pulse tube cryocooler working at 35 K for space application

The attainment and maintenance of a low temperature environment is essential for aerospace cryogenic detectors to achieve their required performance. Developing cryocoolers with features of high efficiency, compact structure, and long lifetime is the main challenge for cryogenic detector cooling. In this paper, a high efficiency thermally-coupled two-stage Stirling type pulse tube cryocooler working at 35 K for HgCdTe long wave infrared detector cooling is designed and tested. The thermally-coupled type avoids gas distribution at cold side which minimizes the inter-stage influence. The whole cryocooler is driven by one linear compressor which enables compact structure. The influence of operation frequency and mean pressure is studied by numerical calculation and experiments to determine the optimum operation condition. Acoustic impedance characteristics of both stages and the whole cold finger are also analyzed by comparing performance of cryocooler with different frequency, mean pressure and structure dimensions. The distributions of acoustic power and phase angle are presented to study the relation between impedance characteristic and the cooling performance. Impedance match between compressor and cold finger is also discussed by analyzing the efficiency of the linear compressor and the performance of cryocooler with different pulse tubes. Under optimum impedance match and operation condition of a working frequency of 39.2 Hz and a mean pressure of 2.45 MPa, the cryocooler provides a cooling power of 1 W at 35.1 K with an input electrical power of 150 W, which indicates a relative Carnot efficiency of 5%. This is a rather high efficiency for developed Stirling type multi-stage pulse tube cryocooler working at 35 K with only inertance tubes as phase shifter. The development of this cryocooler lays a solid base for the further optimization to realize a competitive candidate for aerospace cooling requirements.

Plasma channel dynamics in sub- and microsecond discharges in water

Simulation results of a fast electric discharge and a strong acoustic wave in the water is performed. A theoretical model of a high-current plasma channel is presented. The model accounts for the energy ratio between the input electric power and the plasma channel conductivity, and adiabatic expansion mechanism of this channel in water. It allows you to calculate the dynamics of the expansion of the channel and the generation of a radially diverging acoustic wave. The presented study makes it possible to estimate the probable parameters of the phenomenon: when electric energy is introduced into the channel, its expansion velocity reaches 1.9 km/s, electrons number density in the plasma is up to 2·1020 cm−3. In this case, a strong acoustic wave propagates with a sonic speed (~ 1500 m/s), and the pressure amplitude in the vicinity of the plasma channel can reach 200 MPa. The stability of the model in relation to variations in the initial task parameters has been analyzed. The calculated data for the acoustic wave are in good agreement with the measurements.

HALL-EFFECT THRUSTER ST-25 WITH PERMANENT MAGNET

Results of development and experimental tests of Hall-effect Thruster ST-25 are presented. This thruster is intended for application on small space vehicles. With the purpose of decrease of input electric power in the magnetic system of the thruster a permanent magnet is applied. The permanent magnet is located at the base of the central magnetic core. The permanent magnet provides most of the magnetic induction in the accelerating channel of the thruster, while the side magnets provide precise magnetic field adjustment. Laboratory testing of the ST-25 thruster were realized with application of the preheated hollow cathode which is operated in auto mode at the discharge current 0.5 … 0.9 A. In the process of developing the thruster, its laboratory tests were carried out with a laboratory prototype of the Xenon system for storing and supplying a working substance. The laboratory supply system provided the supply of the working gas to the anode unit 0.65 ... 0.90 mg /s and 0.07 ... 0.10 mg / s to the hollow cathode. The characteristics and parameters of the thruster were obtained using a discharge power supply that has the properties of a voltage source and a power source. The discharge power supply is the part of the flight prototype of the power processing unit. Laboratory tests have confirmed the rightness of the technical decisions stopped up in the structure of the thruster. Methodology of the thruster ST-25 start at the use of preheated cathode and flying prototype of the discharge power supply were improved. Possibility of application of such type of Hall Thrusters on space vehicles with the size of on-board electric power of that is limited to the size 200 - 300 W were confirmed.

Fabrication and Characterization of a Thermophone Based on Laser-Scribed Graphene Intercalated with Multiwalled Carbon Nanotubes.

The low sound pressure level and high operating voltages of thermophones have limited their applications in the past. However, in recent years, utilizing nanomaterials in thermophones has improved their efficiency and applicability. Nanomaterials, especially carbon nanotubes and graphene, have the advantage of low heat capacity per unit area (HCPUA) and high electrical and thermal conductivity. Therefore, they require a low electrical input power and generate a high sound pressure level (SPL) by efficiently transferring heat to the surrounding fluid. Laser-scribed graphene (LSG) can generate smooth spectra acoustic emissions over a wide range of frequencies by means of thermoacoustic (TA) emission. In this work, a thermophone based on LSG intercalated with multiwalled carbon nanotubes (MWCNTs) is proposed. The effects of varying input power, duty cycle percentage and measuring distance on the sound pressure level (SPL) of thermophones are studied to extract maximum efficiency. The achieved SPL of LSG, normalized to the input power, has increased by approximately 11 dB by intercalating it with MWCNTs, which shows that our proposed material can be a potential candidate for an efficient thermophone.

Study on the temperature adaptability of free-piston Stirling heat pump

Heat pump technology can effectively reduce the energy consumption and environmental pollution caused by coal-fired heating. However, commonly used heat pump heating systems have poor performance in low temperature environments, making it challenging to meet the heating demand in cold regions. In this paper, the performance of an electrically driven free-piston Stirling heat pump is studied based on SAGE software. The numerical simulation results show that the 2409 W heating capacity can be obtained with the input electric power of 1 kW, heating temperature of 40 °C and ambient temperature of −20 °C. The overall coefficient of performance reaches 2.41 with corresponding relative Carnot efficiency of 46.2%. In addition, the operation characteristics of this heat pump system under different temperature conditions are investigated in detail. With the constant difference between heating and ambient temperatures, this heat pump can operate efficiently in different temperature ranges. With the increase of temperature difference, the available energy loss in the whole system decreases, leading to the improvement of relative Carnot efficiency. These results show the strong adaptability of the free-piston Stirling heat pump system to different working temperatures.

Evaluation of the Efficiency of a High Temperature Proton Exchange Membrane Water Electrolysis System

In recent years, a significant interest has been growing for the development of high temperature (HT) electrolytes for proton exchange membrane water electrolysis (PEMWE), promising a lower reversible potential and improved reaction kinetics and ionic conductivity.In this study, the energy and exergy analysis developed for PEMWE has been extended to evaluate the performance of HT-PEMWE, with the model aiming to utilise the energy in the most efficient manner and also take into account potential heat losses, which is particularly important considering that these become more pronounced with higher temperature differences.The model shows that the stack operates in autothermic mode over a considerable range of current density. Thus heating inputs to the stack and feed water become progressively unnecessary as polarization losses make up for these heating requirements. For the considered model, a current density above 1.44 A/cm2 would allow surplus heat to be utilised for secondary applications whilst not recovering any heat would result in an exergy efficiency loss of 4.2 % points. The effect of accounting for pipework and stack heat losses is most evident in the lower region of current density. This however diminishes as the losses start constituting a minor fraction of the total power share.The exergy efficiency for HT has been calculated to surpass that for low temperature (LT) at 0.54 A/cm2. This improvement is attributed to a lower electrical power input for the same production of hydrogen and the heat management strategy incorporated within the model. The maximum improvement reaches 3.8 % points at 3 A/cm2. Taking into account exergy favours higher temperature differences – a benefit which outweighs the fact that a greater quantity of thermal power is recovered in the LT system (due to higher polarization losses). This finding also shows the suitability of adopting exergy efficiency as the performance indicator for PEMWE systems.Given the novelty in opting for HT operation, this study offers further understanding on its performance and evaluates the cost borne with opting for more demanding operating conditions from the perspective of energy and exergy efficiency.

FEM-based time-reversal enhanced ultrasonic cleaning

Pipe fouling is a challenging problem in many industrial applications. Current cleaning techniques require halting the production during the cleaning phase and the existing methods are unable to do targeted cleaning, even though fouling is often localized to certain areas inside the pipeline. To address this issue, we use FEM-simulated, time-reversed signals to focus ultrasound power onto a pre-determined location: a fouled pipe residing inside a Plexiglas container. Ultrasound cleaning with similar acoustic power was compared to the time-reversal enhanced method in terms of cleaning efficiency. The cleaning efficiency was determined by measuring how much fouling, by mass, both protocols removed from the surface of a Plexiglas pipe, using similar input electric power and equal cleaning time. Our results indicate that the proposed time-reversal-based technique removes three times more fouling than the standard ultrasound cleaning without focusing. The study extends our previous paper on FEM-based time-reversal focusing [1].

Molecularly Directed, Geometrically Latched, Impulsive Actuation Powers Sub‐Gram Scale Motility

AbstractTransversely curved composite shells of liquid crystal elastomer and polyethylene terephthalate with innervated electrodes present millisecond‐scale actuation with ≈200 mW electrical power inputs at low voltages (≈1 V). The molecular orientation is aligned to direct the thermomechanical work‐content to evert the native curvature. When powered, the curved structure initially remains latent and builds up strain energy. Thereafter, the work content is released in an ms‐scale impulse. The thin‐film actuators are powered against opposing loads to perform up to 10−5 J of work. High speed imaging reveals tip velocities of several 100 mm s−1 with powers approaching 10−4 J s−1. The design eschews bistability. After snap‐through, when the power is off, the actuator spontaneously resets to its native state. The actuation profiles are functions of the geometry and the electrical pulse patterns. The latency of actuation is reduced by powering the actuators with pulses that trigger snap‐through, allow its reset to the native state, but prevent its cooling to the ambient before subsequent actuation cycles. The actuation is harnessed in sub‐gram scale robots, including water‐strider mimicking configurations and steerable robots that can navigate on compliant (sand) and hard (slippery) surfaces. A viable template for impulsive actuation using frugal electrical power emerges.

Key words: Russian Segment of the International Space Station, solar arrays, electric power input, solar array performance estimate, radiation coming from Earth, albedo.

An Experimental Study of Influencing Factors on the Snow Removing Time for Self-Heating Snow Removed Photovoltaic Panels

ABSTRACT Because of the applicability and sustainability, photovoltaic (PV) panels are widely used around the world and attracting lots of academic research interests as one promising application of renewable energy. However, snow issues would decrease the power generating efficiency of PV panels during the winter in cold and snowy regions so that studies of snow-removing methods for PV panels attracted lots of interests. To some extent, current snow-removing methods, either manually or mechanically, have their own deficiencies. Therefore, a novel self-heating snow-removing method for PV panels was proposed in this study, applying a PV panel as an electrical load by supplying it with electric power. To validate this novel method, experiments were carried out and reported in detail in this paper and four influencing factors, snow thickness (4–8 cm), ambient air temperature (−3 to −9°C), input power (170 to 290 W/m2) and the panel tilt (14 to 18º), on the snow-removing time were quantitatively analyzed. Generally, the experimental results showed that increasing the snow thickness, the ambient air temperature, the input electric power and the panel tilt would somehow benefit to the snow-removing process and within the range of the varying parameters the snow-removing time reduction could reach as high as 83.4%. Furthermore, the correlation between the four factors and the snow-removing time was generalized through multiple variables linear regression using obtained experimental data. The comparison between the predicted and tested value showed good agreement, suggesting that the correlation regressed can provide satisfying accuracy when applied to estimating the snow-removing duration in engineering application using the novel snow-removing method proposed in this paper.
