Effect of Cuo-Water Nanofluid on the Thermal - Hydraulic Behavior of Triangular Corrugated Channel

Abstract

The aim of this study is to model and simulate laminar flow and heat transfer in a triangular-corrugated duct containing a CuO-water nanofluid. Note that a temperature is imposed on the walls, the considered Reynolds number (Re) and the nanoparticle volume fraction range from 100 to 800 and 0 to 5% respectively. The basic equations were discretized using the finite volume method. Dynamic and thermal fields were obtained, as well as the Nusselt number (Nu). In addition, the influence of certain parameters (Re, nanoparticle volume fraction) was taken into account. It can be observed that the mean Nu increases with increasing Re. Furthermore, raising the nanofluid volume fraction further enhances the heat transfer. For numerical resolution, we used the FLUENT code. Finally, we note that the results are in excellent accord with experimental ones published in the literature.
