A new multiflow model of a pressurized spout fluid bed with a draft tube has been developed to investigate the voidage and the velocities of particle and gas in spout and annular region.
So I started combing through a bunch of patent drawings for massive industrial sized fluid beds, and I noticed that instead of one big inlet, they all had a bunch of small holes to deliver the air.
