hey all Dears, I am simulating a flow and heat transfert in cavity square porous media look at fig 1



Figure 1

Which method suitable for my problem to derive viscous and inertial loss coefficients?

1. Method: Deriving Porous Media Inputs Based on Superficial Velocity, Using a known Pressure Loss.
2.Method: Using the Ergun Equation to Derive Porous Media Inputs for a Packed Bed
3.Method: Using an Empirical Equation to Derive Porous Media Inputs for Turbulent Flow Through a Perforated Plate.

second as we know in porous media there are 4 models
1-model of Darcy
2-model of Darcy-Forchheimer
3-model of Darcy-Brinkman
4-model of Darcy-Forchheimer-Brinkman
the quastion is how i can use the model of Darcy-Forchheimer-Brinkman in fluent

Thanks

Fluent could only support up to Darcy-Forchheimer model. You could need to write an UDF to represent Brinkman term and hook them inside.

Hi every body
I don't know how determine initial velocity for the flow in porous media.
Thank you for time and consideration.
Best regards
