KR144: How can I set up porous media coefficients given pressure drop versus mass flow rate data?
|
You can typically get a curve fit of pressure drop versus mass flow rate in the form of equation 1 ( refer attached figure) When we compare the values of eq 1 with what Fluent expects, we find the values for viscous resistance Di and inertial resistance Ci. Note: Make sure the units of the calculated resistance coefficients match the units listed in the porous media entry panel. L is the thickness of the porous media zone. |
