Hello，everyone！
I noticed that the carbon particles (yellow colour) stayed still for about 0.33 seconds when I ran the following case, I used the particle_input file to input the initial position of the particle.
I don’t know why this is happening and I hope someone can help me, thanks in advance.
My guess is that particle is too heavy to be fluidized. You could slightly increase the depth of the bed to make sure this is not a wall effect. The depth is currently the same (3mm) as the particle size.
Thanks, I tried to turn down the particle size (2.5mm) but the carbon particles still don’t move at the bottom, is this still due to the wall effect?How do I need to adjust the boundary conditions of the walls?
I was thinking the particle could get stuck between the wall, or wedged by the other small particles. If your particle drops down to the bottom, then it may not be a wall effect, but an insufficient fluidization velocity.
I’ve turned up the flow rate twice as much, but the carbon particles are floating in the free airspace, what can I do?
You should check if the particle reaction rate is reasonable.
