Hello sir i have looked so much but still i am not able to learn how to model fluid flow in ansys fluent. The darcy number i am taking is 0.1 and The particle diameter is 10^-3 t viscous resitance as 10^7 and not considering any inertial resistance but even though i change richardson number from 0.01 to 5 by keeping Gr=10^4

i did not see any signifacent change in total surface heat flux and so in Nusselt number.The solid material is copper and fluid is water.

kindly help if you have any course related to porous media flow kindly let me know i can purchase as well.
