Equilibrium molecular dynamics simulation was used to model a nanofluid system composed of Cu nanoparticles and organic oils as base fluid (eutectic mixture of diphenyl oxide and biphenyl). The base fluid selected was an ...

This study aims at investigating experimentally and analytically the influence of temperature, pressure and solution velocity on the ammonia vapor mass transfer through a microporous hydrophobic membrane and the absorption ...

In the near future renewable energy sources should play an important role in reaching economic competitiveness with fossil fuel for a change in the global energetic scenario in view of the fight against climate change. ...

This work was focused on the study of the drying application distances, or the heated air-obstacle distance, from the condensing unit of the 24000 BTU/hr air conditioning systems (A/C) which effected on the A/C efficiency ...

Biofuels are playing more and more important roles worldwide. While it will reduce the overall emission of greenhouse gases, it may damage the combustion system through corrosion and poor lubrication, and generates ...

The efficiency of expanders is of prime importance for various clean energy technologies. Once mechanical losses (e.g. through valves) are minimized, losses due to unsteady heat exchange between the working fluid and ...

Species, energy and momentum conservation equations are solved in spherical symmetry and under ideal gas approximation, to yield an analytical model capable to evaluate the heat transfer and the evaporation rate from a ...

The vast majority of experimental studies of nanofluids under natural convection have shown that the heat transfer rate decreases in contrast to observations of increased heat transfer rate for forced convection and ...

Experimental work was conducted to study the influence of bulk bed dispersity on contact heat transfer. The contact heat transfer between the inner drum wall to the covered surface of the solid bed was experimentally ...

The aim of this study is to analyze and optimize a vertical axis Savonius-type wind turbine using Computational Fluid Dynamics (CFD). The study is developed in two parts. In the first part of the study, an analysis of the ...
