Prediction of velocity profile of water based copper nanofluid in a heated porous tube using CFD and genetic algorithm

Abstract The heat transfer improvements by simultaneous usage of the nanofluids and metallic porous foams are still an attractive research area. The Computational fluid dynamics (CFD) methods are widely used for thermal and hydrodynamic investigations of the nanofluids flow inside the porous media....
