Effect of Nanofluid on Heat Transfer Enhancement in Rib-Groove Channel

Turbulent nanofluids flows in Rib-Groove channel are numerically investigated. The continuity momentum and energy equations were solved by means of a finite volume method (FVM). A commercial CFD package FLUENT is used to perform the modeling and simulation. Different Rib-Groove shapes are used (Rectangular Rib Triangular RibTrapezoidal Rib Rectangular Groove Triangular Groove and Trapezoidal Groove). Four different types of Nanoparticles (Al2O3 CuO SiO2 and ZnO) with different volumes fractions in the range (0-4)% and different nanoparticle diameters in the range (25-80)nm are dispersed in the base fluid (water glycerin and engine oil) are used. In this study several parameters such as different Reynolds numbers in the range of 5000
