An Investigation on Comparison the Intensification of Heat Transfer in a Baffled Backward Facing Step
Enhancement of turbulent forced convection heat transfer in a channel backward facing step via using different
configurations of turbulators is numerically explored. The turbulators are represented as rectangular and triangular baffles
with staggered arrangement on the top and bottom wall of the channel behind the step. Three values of baffles height is
examined for Reynolds number wide variety up to 105. The governing Navier-Stockes and energy for modeling the
turbulence. CFD commercial code is included to get the solution of a based finite volume discretised algebraic equations.
The findings display that the triangular turbulators pointed the optimum heat transfer intensification as compared with
