Abstract

Abstract

Drift flux model is prevailing for the prediction of void fraction in two-phase flow,whereas distribution parameter C₀ and drift velocity u_gj of the model are an issue argued by different researches until now.This subject is experimentally and theoretically studied in the paper and the limit-ing conditions of distribution parameter and drift velocity for upward two-phase flow are proposed.Fi-nally,the recommended correlation for the void fraction prediction is also presented based on the theo-retical analyses and data comparisons.
