Influence of binary phase flow regimes on the action of sieve plates . Recognition of various flow regimes on sieve plates has greatly enhanced our understanding of the mode of action of these plates. When vapour flow dominates the liquid is dispersed into drops; this is the so‐called „droplet regime”. In a second principal regime, liquid flow predominates and the vapour is dispersed into small bubbles; this is the „emulsion regime”. A transition region exists between these two principal regimes; it is called the „mixed regime”. The present paper attempts to demonstrate the relations between the flow regimes and the characteristics of sieve plates. It considers the structure of the binary phase layer, flow over the weir, axial mixing, entrainment of liquid, maximum loading (flooding), and efficiency.
