Bubble phase voidage and dense phase voidage in thin two-dimensional fluidized beds
Chemical Engineering Science, 1986 Bubble phase and dense phase voidages have been studied in a series of thin two-dimensional fluidized beds using a light transmission technique. It is proposed to divide the bubble phase voidage into a "visible" and an "invisible" portion with respect to

Bioreactors with Light-Beads Fluidized Bed: The Voidage Function and its Expression
Acta Universitatis Cibiniensis. Series E: Food Technology, 2014 Light-beads fluidized bed bioreactors with gel particles are an attractive alternative for the implementation of a system with immobilized cells. They have a number of advantages: soft operating conditions, ability to work in an ideal mixing regime ...

MEASUREMENT OF VOIDAGE IN THE FOUNTAIN OF A SPOUTED BED.
The Canadian Journal of Chemical Engineering, 1986 A gamma -ray technique is described for measuring the distribution of fractional voidage in the fountaion of an air spouted bed. Experimental data on fountain voidage are presented. For the relatively shallow, 160 mm diameter, conical spouted bed studied,
