Experimental and Numerical Investigation of Heat Transfer Augmentation Using Al2o3-Ethylene Glycol Nanofluids Under Turbulent Flows in a Flat Tube

A study of computational fluid dynamics has been conducted to study the characteristics of the heat transfer and friction factor of Al2O3/Ethylene glycol-water nanofluid flowing inside flat tube. The three dimensional realizable k?e turbulent model with an enhanced wall treatment was utilized. The e...
