Default A question about gas-solid fluidized bed!
Posts: n/a
how to get the pressure fluctuation at some point in a fluidized bed? After setting up a point closed to the bed wall,I define a mixture pressure.But the curve output dosen't fluctuate.whether the time step or grid interval size has some faults? I am so puzzled! Wish for your help. Thanks !
