Numerical study of convective heat transfer and of turbulent forced of differents Nanofluids in channel

Abstract

In this study, the flow field and heat transfer of differents nanofluids (AL2O3, CuO, SiO2, ZnO), turbulent forced convection in a channel. The surface of the channel is hot Th= 310 K. Simulations are carried out for constant water Prandtl number of 6.99, Reynolds numbers from 20,000, 30,000, 40,000, 50,000 to 60,000, nanoparticles volume fractions of 0, 0.01, 0.02, 0.03, 0.04 and nanoparticles diameter of 30 nm. The finite volume method and SIMPLE algorithm and k-e are utilized to solve the governing equations numerically. The numerical results showed that with enhancing Reynolds numbers and volume fractions, average Nusselt number increases.
