zero velocity in fluidized beds

December 17, 2002, 02:06

Hi everyone....

here i have a silly question to ask.. do anyone try zero velocity on the fluidized bed?? I mean no flow pass through the bed....

I have tried it and found that the particles fluidized as usual??? WHY??

Is that this my setting wrong or is the FLUENT limitation??

can anyone help me about this?? thank

You have to be careful with zero velocities. While I'm not that familiar with fluidized beds, many of the equations used to model various phenomena degenerate at v = 0.
