In the present study the effect of fin spacing and Reynolds number on the convection of heat and fluid flow is investigated for the Reynolds number ranging from 1200 to 2000 by using both time and spaced averaged tubulence models such as the Standard k-ε model, nonlinear RNG k-ε model and Large Eddy Simulation (LES). The average Nusselt number, pressure coefficients and vorticity distributions are determined for the various fin spacing conditions at different Reynolds numbers for all turbulence models and the values of these governing parameters are compared with each other.
