Abstract
A method of analyzing heat and mass transfer in gas-liquid two-phase flow in an object transfer system includes dividing the object heat transfer system into a plurality of nodes, calculating a void fraction in a gaseous phase above a liquid surface of a node and calculating a void fraction in another node beneath the first node, and calculating a liquid surface level based on the results of the previous steps.
