Abstract
Laminar forced convection heat transfer from 2-D flow over a square cylinder placed in a confined adiabatic channel is studied numerically. The governing equations are solved using unsteady stream function-vorticity method. The effect of volume fraction of the nanoparticles are tested for different Reynolds number in laminar range. Fluid dynamics and heat transfer results were reported for steady-state condition. Local Nusselt number and average Nusselt number are reported in connection with volume fraction and Reynolds number for blockage ratio of 0.25. Square cylinder’s front wall results maximum Nusselt number whereas rear wall shows smaller Nusselt number. Wall attached pair of vortices appeared rear side of cylinder for Reynolds number varying from 10 to 40 and volume fraction varies from 0.0 to 0.1. The size of symmetry vortices linearly increases when Reynolds number or volume fraction is increased. The drag coefficient is more pronounced to the variation in Reynolds number and volume fraction rather lift coefficient.
