A Proton Electrolyte Membrane fuel cells (PEMFC) is considered to be a viable alternatives Internal Combustion Engines (ICEs) in automotive applications due the key advantages thermal management system. The main duty of system maintain desirable temperature, with uniform temperature distribution across stack and.its.individual membranes. In this paper, enhancement PEMFC cooling plate was analys...

for better understanding the effect of nanofluid flow in a porous medium, a set of experiments were conducted on a horizontal glass micromodel for al2o3-water nanofluids. to characterize the flow of nanofluids the same experiment was done by pure water. the glass micromodel was constructed by a photolithography technique. the al2o3-water nanofluids were produced by a two-step method and no surf...

The rheological behaviour of ethylene glycol-based nanofluids containing hexagonal scalenohedral-shaped α-Fe2O3 (hematite) nanoparticles at 303.15 K and particle weight concentrations up to 25% has been carried out using a cone-plate Physica MCR rheometer. The tests performed show that the studied nanofluids present non-Newtonian shear-thinning behaviour. In addition, the viscosity at a given s...

The low conversion efficiency of solar cells produces large amounts of thermal energy to the cells, and with an increase in the temperature of solar cells, their electrical efficiency decreases. Therefore, a hybrid photovoltaic thermal system improves the overall efficiency of the system by adding thermal equipment to the solar cell and removing excessive heat from these cells. In this paper, w...

In recent years, hard turning has been found to be a well-known substitute for traditional grinding acquiring the finish quality of hardened steel without sacrificing productivity. There are many issues that should carefully understood and dealt with attain efficacious performance in turning. This article discusses modern manufacturing challenges focus on analyzing current state art process ter...
