Harvested from ORCID Public Data FileXiaojia Wang in OpenAIRE Nuo Yang; Nuo Yang;The acoustic mismatch model and the diffuse mismatch model have been widely used to predict the thermal interface conductance. However, the acoustic mismatch model (diffuse mismatch model) is based on the hypothesis of a perfectly smooth (completely disordered) interface. Here, we present a new modified model, named as the mixed mismatch model, which considers the roughness/bonding at the interface. By taking partially specular and partially diffuse transmissions into account, the mixed mismatch model can predict the thermal interface conductance with arbitrary roughness. The proportions of specular and diffuse transmission are determined by the interface roughness which is described by the interfacial density of states. It shows that the predicted results of the mixed mismatch model match well with the values of molecular dynamics simulation and experimental data. 20 pages, 9 figures, 1 table

Harvested from ORCID Public Data FileSwellam W. Sharshir in OpenAIREAbstract This paper offers a hybrid solar desalination system comprising a humidification-dehumidification and four solar stills. The developed hybrid desalination system reuses the drain warm water from humidification-dehumidification to feed solar stills to stop the massive warm water loss during desalination. Reusing the drain warm water increases the gain output ratio of the system by 50% and also increased the efficiency of single solar still to about 90%. Furthermore, the production of a single solar still as a part of the hybrid system was more than that of the conventional one by approximately 200%. The daily water production of the conventional one, single solar still, four solar still, humidification- dehumidification and hybrid system were 3.2, 10.5, 42, 24.3 and 66.3 kg/day, respectively. Furthermore, the cost per unit liter of distillate from conventional one, humidification- dehumidification and hybrid system were around $0.049, $0.058 and $0.034, respectively.

Harvested from ORCID Public Data FileSwellam W. Sharshir in OpenAIREAbstract In this paper, a theoretical comparative study between modified solar stills (MSSs) and classical solar still (CSS) was carried out, based on the productivity and the thermal properties. The MSSs contain brackish water mixed with either graphite or copper oxide (CuO) micro/nano particles. Cost estimations of solar still desalination by using micro/nano particles was estimated. exergy destruction in various components of the solar still (SS) were calculated, analyzed and discussed. The exergy loss during the day time comprises the exergy destruction in the main components of the SS like basin plate, brine water, glazier plate and insulation material. The hourly convective, evaporative and radiative heat transfer coefficients (HTCs) with and without micro/nano particles were determined. The exergy destruction in various components of the SS have been analyzed and a solution was suggested. Results revealed that the exergy of evaporation, energy efficiency and exergy efficiency of MSSs were higher than that of the classical one. The daytime energy efficiencies of MSSs with graphite and CuO were 41.18% and 38.61%, respectively, but for the CSS was only 29.17%. The diurnal productivity of the MSSs was increased by 41.18% and 32.35% for graphite and CuO, respectively, compared with CSS. Moreover, the diurnal exergy efficiencies of MSSs were 4.32% and 3.78% for graphite and CuO respectively, while exergy efficiency for CSS was 2.63%. Furthermore, the costs of water production were found to be approximately 0.20, 0.21 and 0.24 RMB/L (1 RMB = 0.15 US $) when using MSS with CuO, MSS with graphite and CSS, respectively.

In this article, an integrated system combining thermoelectric heating and cooling is introduced, which not only improves the overall energy efficiency but has a great potential for applications in air sterilization and purification. In the proposed system, the air is firstly heated up for air sterilization by fins thermally grounded to the hot side of multiple thermoelectric devices. The air is then cooled down by the cold side of the same thermoelectric devices. The heat exchange and flow conditions of the system are analyzed, and it is found that the Nusselt number ratio after adding the fins is increased by two times compared with the smooth tube. The air temperature in the system can reach up to more than 65°C using multiple thermoelectric devices. Such a temperature is able to inactivate many viruses. The coefficient of performance of the overall system can reach 5.4. This work demonstrates new applications of thermoelectric devices for energy-efficient air sterilization applications.

Machine learning's application in solar-thermal desalination is limited by data shortage and inconsistent analysis. This study develops an optimized dataset collection and analysis process for the representative solar still. By ultra-hydrophilic treatment on the condensation cover, the dataset collection process reduces the collection time by 83.3%. Over 1,000 datasets are collected, which is nearly one order of magnitude larger than up-to-date works. Then, a new interdisciplinary process flow is proposed. Some meaningful results are obtained that were not addressed by previous studies. It is found that Radom Forest might be a better choice for datasets larger than 1,000 due to both high accuracy and fast speed. Besides, the dataset range affects the quantified importance (weighted value) of factors significantly, with up to a 115% increment. Moreover, the results show that machine learning has a high accuracy on the extrapolation prediction of productivity, where the minimum mean relative prediction error is just around 4%. The results of this work not only show the necessity of the dataset characteristics' effect but also provide a standard process for studying solar-thermal desalination by machine learning, which would pave the way for interdisciplinary study.

To overcome this problem, there is a demand for some supportable sources for the water purification. Solar still is a valuable device that can be used for purifying of brackish and salt water for drinking purposes. In this article, a review of factors affecting solar still production (climatic conditions, operations and design parameters) and enhancement techniques (wicks, internal and external condensers, internal and external reflectors, phase change materials, Stepped solar still and a new method improved the solar still yield by using nanoparticles) has been argued. Using sponge cubes in the basin water caused a significant enhancement in solar still production (up to 273%) whereas using cuprous oxide nanoparticles increased the distilled yield by 133.64% and 93.87% with and without the fan respectively.

In this work, we proposed a solar steam generator using wick material with wrapped graphene nanoparticles, and the energy efficiency can reaches up to 80%. Instead of traditional smearing method, the chemical wrapping method was used to better adhere the graphene nanoparticles on the wick materials. Through the SEM morphological results, the graphene nanoparticles are shown to be evenly wrapped across the fibres of the wick material, which have better dispersity and stability. The evaporation rate, instantaneous energy efficiency and the absorptivity of three wick materials with/without nanoparticles under different conditions were compared and analyzed. Among the three different wick materials, the flannel cloth with dense fine hairs can provide three-dimensional contact area for wrapping graphene nanoparticles and thus contribute to better evaporation. Additionally, the influence of two different reduction methods and different concentrations of graphene oxide solution on the energy efficiency was also discussed. Our work offers a simple and effective way of using nanotechnology in practical application for solar steam generation.

Harvested from ORCID Public Data FileAmmar H. Elsheikh in OpenAIREAbstract Over recent decades, the global demand for freshwater is increasing rapidly; however, the supply of freshwater is limited. Solar still (SS) is a valuable solar device that is used for converting the brackish and saline water into purified water. Several investigations depicted in literature have been performed, either experimentally or theoretically, on SS to assess its performance under different climatic and operational conditions. Apart from experimental studies, theoretical analysis is beneficial for evaluating the effectiveness of virtually designed SS. The theoretical analysis and simulation modeling of SSs can provide clear understanding on the mechanics, which may give directions on the design setup in experiments. In this review different theoretical approaches which have been used to assess the thermal performance of SS and exergy analysis of such devices are discussed. The reviewed studies indicate that the productivity of the SS depends on different external and internal operating parameters. In addition, the distillate quantity varies according to the design features and the related technical advancements of the SS. Our findings indicate that there are still few more parameters and design aspects to be considered while designing new SS. The objective of this paper is to highlight design methods so as to allow the researchers to optimize the SS for further development. Recommendations for further research have been also proposed.

In this paper, we modified the conventional solar still. The outdoor performance of modified solar stills was studied to assess its potential for real application. The modifications include using flake graphite nanoparticles (FGN), phase change material (PCM), and film cooling. In the presence of the three previous modifications, the productivity was enhanced as high as 73.8% compared with that of the conventional still. The effect of water depth on the enhancement was also investigated. It shows that the enhancement of productivity increases by around 13% when the water depth decreases from 2 cm to 0.5 cm. Besides, an indoor experiment was carried out to analyze the enhancement mechanism by FGN. It shows that the increase in both temperature and saturated vapor pressure contributed to the enhancement.
