Summary

VAPOUR CONDENSATION RATE INSIDE HORIZONTAL CONDUITS WAS STUDIED FOR CO-CURRENT AND COUNTER-CURRENT FLOW OF STEAM AND THE ACCUMULATED CONDENSATE AT THE BOTTOM OF THE TUBE. WHEN COMPARED WITH THE CO-CURRENT FLOW CASE, THE INTERFACIAL SHEAR INCREASES THE AXIAL PRESSURE DROP IN THE COUNTER-CURRENT CASE AND DECREASES THE EFFECTIVE TRANSFER SURFACE. THE EFFECT OF CHANGING THE INCLINATION ANGLE OF THE TUBE FROM 1 TO 2 DEG FROM THE HORIZONTAL ON THE HEAT TRANSFER RATE IS RELATIVELY UNIMPORTANT. FOR A GIVEN TUBE LENGTH, CO-CURRENT FLOW IS THE RECOMMENDED MODE OF OPERATION WHEN A HIGHER CONDENSATE PRODUCTION RATE IS DESIRED AT A GIVEN TEMPERATURE DRIVING FORCE.
