摘要
The transition from froth to spray regime on sieve trays was experimentally studied in an air/water simulator with 300 mm diameter. It has been found that the regime transition occurs as the cleax liquid height is equal to the residual pressure drop on the trays. A convenient and accurate technique was proposed for determination of the regime transition point. ]Based on analysis of the transition process at a sieve hole, a new formula which can be used to correlate the experimental results was provided.
