Dalgalı Mikrokanalda Nanoakışkanların Laminer Akışta Isı Transfer Performansının Sayısal Olarak İncelenmesi

Abstract

Our study has been investigated nanofluids' heat transfer performance in a wavy microchannel using theoretical and computational fluid dynamics. Al2O3, CuO, Fe2O3, TiO2 and SiO2 have been used in the calculations as nanoparticles. Volumetric nanoparticle ratios in the nanofluid are 1%, 2%, 3% and 4%. Outlet temperatures, Nusselt number, thermal conductivity efficency and convective heat transfer coefficients of nanofluids at 100, 250, 500 and 1000 Reynolds numbers have been investigated. It observed that the heat transfer performance increased thanks to the increasing Reynolds number and the increasing percentage volumetric nanoparticle ratio.
