A STUDY OF THE EFFECTS OF SHIPS MOTION ON FREE-SURFACE STEAM-WATER SEPARATION
A study of the liquid--vapor separation problem was undertaken. Particular attention was paid to the carryover problem and carryunder problem. Expressions or methods for evaluating the liquid carryover were obtdined. The same was done for the vapor carryunder problem; i.e., the vapor carried along with the liquid in the return line from the separator. A flow model was established and the analysis for the carryover problem imposed the condition that the shear and liquid gravitational forces balanced at the liquidvapor interface with zero liquid velocity. Also, the flow over the bubbles at the liquid-vapor interface was laminar so that the shear stress was inversely proportional to the liquid film thickness. For the carryunder problem, the vapor bubble bcuyancy and drag forces were equated to determine permissible liquid velocities in the downcomer. (auth)
