Turbulent Forced Convective Flows in a Horizontal Channel Provided with Heating Isothermal Baffles
This work presents numerical results of turbulent forced convection in a horizontal channel provided with heating two baffles mounted on its lower wall. The upper and lower surfaces are maintained at the high temperature and the fluid inlet temperature is lower than the temperature of the walls. Calculations are made by using a finite volume method and an efficient numerical procedure is introduced for studying the effect of inclination angles on heat transfer and flow field for air and high Reynolds number. Results are reported in terms of streamlines, isotherms and local Nusselt numbers. Overall, we can conclude that the results of the study show that the inclination angles of the heated plate alter significantly the temperature distribution, the flow field and the heat transfer in channel.
It was found that the total heat transfer in a horizontal channel mounted the obstacles is increased under effect increase of inclination angle of baffle.
