Different modes of gas injection in 2-dimensional fluidized beds of group B and group D particles are detected by pressure fluctuations at the orifice and in the bed. Frequencies of bubble generation and coalescence from photog. observation agree with those from the anal. of pressure signals. Pressure perturbations spread from the jetting region at much higher velocities than predicted by available theories.

Abstract
Different modes of gas injection in 2-dimensional fluidized beds of group B and group D particles are detected by pressure fluctuations at the orifice and in the bed. Frequencies of bubble generation and coalescence from photog. observation agree with those from the anal. of pressure signals. Pressure perturbations spread from the jetting region at much higher velocities than predicted by available theories.File in questo prodotto:
