Summary

AN ANALYTICAL MODEL HAS BEEN DEVELOPED FOR PREDICTING VOID FRACTION IN TWO-PHASE ANNULAR FLOW. IN THE ANALYSIS, THE LOCKHART-MARTINELLI METHOD HAS BEEN USED TO CALCULATE TWO-PHASE FRICTIONAL PRESSURE DROP AND VON KARMAN'S UNIVERSAL VELOCITY PROFILE IS USED TO REPRESENT THE VELOCITY DISTRIBUTION IN THE ANNULAR LIQUID FILM. VOID FRACTIONS PREDICTED BY THE PROPOSED MODEL ARE GENERALLY IN GOOD AGREEMENT WITH AVAILABLE EXPERIMENTAL DATA. THIS MODEL APPEARS TO BE AS GOOD AS SMITH'S CORRELATION AND BETTER THAN THE WALLIS AND ZIVI CORRELATIONS.
