Abstract ：
The effects of cold surface temperature, wet air state (temperature and humidity) and original drop size on frost dendrites growth of two neighboring separate frozen water drops of same size under natural convection conditions were investigated by quantitative measurement. It was determined that for different cold plate surface temperature conditions, i.e., the ordinary-low temperature and the cryogenic temperature range, the frost formation mechanism is different. Under the conditions that the air temperature is not too high and absolute humidity is not too excessive, the influence of frozen water drop size on the longest dendrite of frost crystals becomes more and more obvious with the decrease in cold plate temperature. The changes in air temperature and relative humidity both change air absolute humidity, so they have similar effects on the growth of dendrites. However, the effect of wet air state on the growth of frost dendrites is not monotonous, which needs to be considered comprehensively in combination with heat and mass transfer and the existence of heavy phase layer. The thickness of 'the initial continuous frost layer' was measured and it was disclosed that the initial frost layer thickness is 1.7-3.0 times that of the height of the frozen water drop diameter. This value may be possibly used as initial frost layer thickness in heat and mass transfer-based frost layer growth prediction models, at least for ordinary-low temperature conditions.

Abstract ：
Quantitative measurements were carried out of the dendrite frost crystal growth under natural convection conditions on a frozen water drop sitting on a cold surface whose temperature is as low as-190 degrees C to study the effects of cold surface temperature, wet air state and original water drop size. In order to classify the influences of different cold surface temperature regions, the frost crystal dendrite growth of both ordinary-low and cryogenic cold surface temperatures were investigated. It was found that the cold plate surface temperature has a direct influence on frost formation mechanism. Decreasing the cold surface temperature for ordinary-low cold surface temperatures will enhance and for cryogenic cold surface temperatures will suppress the frost crystal dendritic growth of the frozen water drop. The measurements disclosed that the length of the longest frost crystal dendrite grows almost linearly with time, esp. in the early stage. The effects of the water drop sizes on the longest frost crystal dendrite growth become more and more obvious as the cold surface temperature decreases. The influence of air relative humidity on the frost crystal dendrite growth is something similar to that of air temperature under given conditions, since their change both changes the absolute air humidity. A very peculiar phenomenon, i.e. the influence of wet air state on frost crystal dendrite growth is not monotonous, was observed. These findings are important for understanding and studying the frost formation and growth, especially the initial frost formation period, on low temperature surfaces.

Abstract ：
A CFD model with chemical reaction kinetic and heat and mass transfer for a monolith reactor is established by COMSOL Multiphysics to investigate the influence of different operating conditions and water on denitrification efficiency for Cu-CHA. At the low temperature range, water has little effect on the denitrification efficiency over the Cu-CHA catalyst while NO conversion is increased by about 30% at the medium temperature. The concentration of O-2 (C-O2) has no significant effect on the performance of Cu-CHA catalyst. The best ratio of NO2 to NOx in feed gases may be 1/2, which improves the denitrification efficiency and the yield of N-2 but it produces relatively little N2O. The optimal ammonia-nitrogen ratio is 1.1, where Cu-CHA catalyst has fairly great denitrification efficiency and low NH3 leakage. Increasing inlet flow velocity and cross area of channels have negative effect on NO conversion, while longer channels and thicker substrate have the opposite effect.

Abstract ：
In this study, a visualizable experimental platform of steam ejector oriented towards MED-TVC desali-nation system is constructed, and the evolution laws of two-phase choking flow and ejector's entrain-ment performance under various operating parameters are obtained. Further, a matching double-choking theory with consideration of the condensing flow is developed to explain the inherent reason behind these evolution laws. Key results revealed that the formed two-phase choking flows have great effects on ejector's entrainment performance. The primary jet flow choking area linearly increases as the primary steam pressure raises, and the entrainment choking area experiences a small reduction, while the extended flow area marginally increases. Accordingly, the entrainment ratio significantly decreases, while the choking cross-section is slightly shifted upstream. In addition, the primary jet flow choking area considerably decreases with increasing entrainment pressure, but the entrainment choking area is nearly unchanged and the extended flow area increases by more than 8 times. As a result, the entrainment ratio remarkably increases, the choking cross-section migration distances are much larger than that in the case of primary steam pressure varies. A meaningful guide evolves from fact that priority should be given to restrain the condensing flow for achieving a higher energy efficiency of ejector. (c) 2021 Elsevier Ltd. All rights reserved.

Abstract ：
Microbial fuel cells (MFCs) are a promising biotechnology that realizes the transformation of wastewater treatment from an energy consumption to an electricity generation process. However, the tedious process and the large resources consuming in preparing powder ORR catalysts are still non-negligible limiting factors for application. This study aims at proposing an energy-efficient method for preparing three-dimensional binder-free air cathode for MFCs: non-noble composite catalysts based on graphene and MnO2 are synthesized directly on stainless steel fiber felt (SSFF) by pre-fixing and electro-reducing graphene oxide on SSFF (rGO-SSFF), and then in-situ depositing MnO2 nanocatalysts on rGO-SSFF (rGO@MnO2-SSFF). The experimental results show that the ORR ability of rGO@MnO2-SSFF cathode is greater than that of Pt/C-CC cathode, even if the performance of rGO@MnO2 powder catalyst is slightly lower than that of the traditional Pt/C catalyst. The excellent performance is found to be due to the three-dimensional framework-pore structure of SSFF which helps the prepared cathode possess larger electrochemical active area (8415.18 m(2) m(-3)) than Pt/C-CC cathode (7518.13 m(2) m(-3)). The proposed method provides a new way to reduce the cost (labor, materials and energy) of air cathode while ensuring the high electricity output of MFCs. (C) 2021 Elsevier Ltd. All rights reserved.

Abstract ：
Flow and heat transfer characteristics of oil-based drilling cuttings in a screw-driving spiral heat exchanger were numerically simulated. The influence of spiral tube rotation speed, Reynolds number of oil-based drilling cuttings, cross-sectional shape on flow and heat transfer characteristics were studied. The results show that with rotation speed increases, the heat transfer coefficient and outlet temperature of oil-based drilling cuttings all increase. In addition, when Reynolds number is less than 250, Nusselt number increases rapidly with the increase of Reynolds number, and Reynolds number has little influence on Nusselt number when it is more than 250. Besides, Nusselt number increases with the increase of curvature ratio di=D. In order to facilitate engineering design, a correlation for heat transfer of oil-based drilling cuttings flowing in the shell side of the heat exchanger is obtained. © 2021, Science Press.

Abstract ：
Hydrophobic surface has been used for restraining frost deposition on cold non-transparent surfaces. However, anti-frosting surfaces with good transparency, esp. transparent hydrophobic surfaces are receiving more and attention from both industries and researchers. A simple method for preparing transparent hydrophobic surface is thus proposed and used to fabricate anti-frosting hydrophobic surfaces. A series of frosting experiments on transparent hydrophobic surfaces and unmodified glass surfaces were carried out under natural convection conditions. The results show that the maximum contact angle of the modified hydrophobic surface is increased by 39.3 degrees, which means an increase of 44.1% over that of the unmodified plain glass surface. The surface properties are the best when TEOS addition is 10 mL. In the range of visible light, the surface transmittance is greater than 87%. A very special condensate droplets freezing mechanism, i.e., the ice bridge mechanism is observed. And the frost crystal appearance time on the hydrophobic surface is more than 660 s, which is 540 s longer than that on the unmodified glass surface. The frost coverage of the hydrophobic surface is significantly smaller than that of the unmodified plain glass surface, the speed of frost propagation is only 47.5 mu m/s, which is 29.6% lower than that of unmodified surface. Therefore, compared with the unmodified surface, the hydrophobic glass surface can effectively inhibit the growth of frost layer without much loss of its transparency. (C) 2021 Elsevier Ltd and IIR.
