I have calculated the drag coefficients (c1 and d1) from the umf file by MFiX. The question is; Does adjusting c1 and d1 and using the velocity from the experiment have the same effect as using the default c1 and d1 while multiplying the velocity by a factor to compensate the change?
I’m asking because the case is diverging as I changed the c1 and d1 values.
Here is the file:
