Relationships giving spout diameter as a function of height are developed for both twodimensional and cylindrical spouted beds, and tested against experimental data selected from the literature. The required input information includes the average spout diameter and the spout expansion angle. The for

## Abstract Minimum spouting velocity was measured using different bed heights with six different particles. A statistical analysis of the reported correlations for minimum spouting velocity based on the present and literature data was made and the estimated. Absolute average relative deviation (AA
Das Geschwindigkeitsverhaltnis wird darin aus der Partikelsinkgeschwindigkeit, bei der die Verteilungssumme der Partikeln 50% betragt, zur mittleren Fluidgeschwindigkeit bestimmt.

## INTRODUClTON The advantages of a spouted bed are well known for physical processes with coarse particles. These. processes involve drying, particle coating, granulation and heat transfer operations (Mathur and Epstein, 1974). The fluid from an inlet orifice penetrates through a bed of particle
