Numerical Investigation of the Use of Boron Nitride/Water and Conventional Nanofluids in a Microchannel Heat Sink

The purpose of this paper is to study the effects use boron nitride (BN) and other conventional nanoparticles (Al2O3, CuO TiO2) on pressure drop heat transfer in a microchannel. governing equations for forced fluid flow were worked out by using fluent computational dynamics (CFD) code. Computational results collected from CFD code Al2O3 as nano-particle compared with numerical values used literature validation. basis water-cooled (pure water, Al2O3/Water, CuO/Water, TiO2/Water BN/Water) smooth microchannel was outlined, then corresponding laminar evaluated numerically. tests (NT) express good agreement found literature. These also indicate, through comparison which performed taking loss parameters between BN widely into consideration, that more favorable nanoparticle. In common TiO2), enhances slightly raised losses owing its high thermal conductivity velocity profile because low density. It chemically stable at highest temperature relative most solid materials. Thus, it has structure can be cooling systems long time without causing problem agglomeration.
