Boundary condition - FFT
Boundary condition - FFT
I am working on simulating a two-phase flow 3-D fluidized bed. It is a granular flow interacting with gas. When I created my mesh, the bottom part was declared as a “velocity-inlet”. Mainly walls on the sides and the top part is the outlet. My question is: I am not sure if I should declare it as “outflow” or “pressure-outlet”.:eek: Can somebody tell what is more appropriate and explain me the difference between them? The reason why I am asking the above question is because I am also trying to get the FFT (Power Spectral Estimate) x frequency graph of the vertical forces. Thank you! :D |
After asking some people, I got the answer to my question.
It might help others so I decided to post. Since it is a two-phase flow, it is more apropriate to use "outflow". "Pressure-outlet" is used mostly for gas. |
hi ..did u completed 3d fludized bed simulation ..can u send case n data file to me plzzz.
if u dont have help me out plz..i have some doubts pertaining to udf and under relaxation factors ... thx for telling it outflow . Its been very helpful for me thx for replying in advance |
