Abstract: Numerical simulations of laminar ?low complex for convective heat transfer through a 2D channel wall forward facing steps using different type of nano?luids having a baf?le. The Finite Volume Method (FVM) solved by equations, momentum, continuity and energy equations and the SIMPLIC calculation plan is connected to look at the impacts of the baffle wall in ?low, characteristics, and convective thermal enhancement. Four distinct sorts of nano?luids [Al2O3, SiO2, CuO, and ZnO], with various volumes of particles in the scope of 0.01 to 0.04 scattered in the base liquid (water) are utilized. The effects of height Hb and width Wb of baffles, on Nusselt number variety are numerically simulated. The results demonstrate that SiO2 has the most astounding Nu contrasted and different nano?luids. The distribution district and Nu increment as the volume of nanoparticle increments and it diminishes as the particle’s diameter increments.
