• Experimental and numerical results on heat transfer in PCM/foam are presented. Morphology, orientation effects, IR-camera melting front tracking, shown. Melting fraction comparisons show a good agreement for all cases. Liquid phase velocities shown to appreciate morphology effects. Porosity has higher impact compared PPI orientation. Phase Change Materials (PCM) promising materials thermal en...

The rechargeable metal-air battery technology is a well-interested smart method for eco-friendly and sustainable energy storage. Both of the two order magnitude lower global market price per tonne Zn compared to lithium multiple theoretical practical specific density ZAB worldwide Li-ion designs contributes developing continuously Zn-air battery. air electrode as cathode has vital role in incre...

The present work was aimed to examine the effects of incorporation of each of two different types of nanoclay, i.e. Cloisite Na+ and Cloisite 30B, into PVA foam on cellular morphology and water absorption capacity. Foam samples containing 0.0-10.0 wt% of each of the two types of nanoclay alone were prepared using mechanical foaming. Accordingly, PVA/organoclay/water suspensions were prepare...

The performance of an electronic radiator filled with metal foam a porosity 96% was studied. effect the factors including flow rates, pores per linear inch (PPI) and numbers fins analyzed. results show that reflects stronger ability heat transfer compared to without foam. With increase in rate between 10 L/h 60 L/h, coefficient both two radiators will be improved, but it is also dependent on nu...

Optimizing the flow field of solid oxide electrolysis cells (SOECs) has a significant effect on improving performance. In this study, metal foam in high temperature SOEC steam is investigated by three-dimensional model. The simulation results show that performance improved using as gas field. conversion rate increases from 72.21% to 76.18% and diffusion flux 2.3 × 10?4 kg/(m2?s) 2.5 at 10,000 A...

In this work, a paraffin- metal foam composite were prepared by the vacuum impregnation method. Aluminum and nickel foams used. The aim of study is to characterize thermal behavior these composites with view their use for management Li-ion batteries. First, conductivities diffusivities in solid state evaluated using Hot Disk Thermal Constants Analyzer (TPS 2500S) Transient Guarded Plate Techniq...

This investigation presents the effect of various parameters on foam stability and its rheological properties. The underlying idea of this experiment is generating of drilling foam with uniform bubbles. The main problem of foam using is controlling its stability during field application. The most important parameters which cause Instability in foam are gravity drainage, gas diffusion and bu...

Due to the manifold properties of porous materials in general, and metal foams particular, they are increasingly used industrial, structural functional applications. The depend on: chemical composition, metallurgical aspects, processing morphology (the type porosity: open or closed), amount porosity, cells size shape. There challenges difficulties encountered welding bonding from wider use prod...
