[Development of a "vortex bed" drying apparatus].
Fundamental parameters in dimensioning a "vortex bed" drying apparatus are the pressure drop across the bed and the higher and lower limit of fluidization velocity. The analysis of the Navier-Stokes equations brings to the following functional relations between dimensionless groups: (see journal). These relations define the fluidization conditions in a "vortex bed" apparatus. Experimental tests carried out on a laboratory scale apparatus will provide us with the unknown constants for industrial scale extrapolation.
