Laminar flow modeling of different nano fluids around a flat plate fin for geometry optimization of a heat sink

This paper presents a mathematical modeling for geometryoptimization of a rectangular cross-section flat plate finusing different nano fluids with water as based fluid. Flowimpinging on the fin is considered laminar. The effects ofReynolds number, volume fraction of nanoparticles, particlesize, inlet velocity and different average temperature on thegeometry optimization of the fin are investigated. Arectangular flat plate fin is made from copper with highthermal conductivity. Various nanofluids with differentvolume fractions and different nanoparticle sizes arestudied. In this analysis, as a basic assumption, the length ofthe fin is taken larger than the width and the fin volume isconsidered constant. Then, width of the fin will beoptimized. The results indicated that the highest and thelowest optimized width is related to gold and silicon dioxidenano fluids respectively.
