The necessity for improving the thermal performances of the solar air collector, for some needs, encouraged us to carry out this study. Initially, to improve the efficiency factor of these solar collectors, we create an increasingly turbulent flow between the absorber and the back wooden plate....

Within the thermal energy capture and/or storage systems currently available or investigated, PCMs are the sole latent heat stores. Despite their low thermal conductivity, that limits charging and discharging times, the higher energy storage capacity per unit weight in comparison with sensible...

A numerical three-dimensional non-isothermal hydrodynamic and thermal modeling based on the unidirectional flow analysis of stratified flow in the circular cross section pipe is developed and tested by experimental data. The model could solve the steady axial momentum equation and heat transfer...

An analytical overview of experimental results about the heat transfer capabilities of nanofluids is presented, using widely scattered available information from diverse literature sources. It is shown that, despite the large number of publications available about this issue, only few studies...
