thank you, I find the third argument has a linear relationship with friction pressure. When it is equal to the solid volume fraction, the calculated friction viscosity is equal to the fluent model...

The modified udf is as follows，pc is still equal to 0.I don't know how to modify it further. I also don't know the Property_ID of frictional viscosity . I hope you can help me.
Thank you in...

thank you!
I use this property ID, but the result is all 0. I think my UDF is written correctly, I can get accurate results by using PROP_rho as property ID.So where did I wrong??
Thank you in...

Friction pressure by Johnson and Jackson model

Dear all,

I'm simulating a multiphase flow using Fluent with air and a granular phase (TFM approach). I used the Johnson and Jackson model to calculate the friction pressure, and I also wrote a...
