Gas-liquid mixed phase flow analysis method, gas-liquid mixed phase flow analysis device and computer program

摘要

Problem to be solved: to provide a new and improved gas-liquid multi-phase flow analysis method capable of performing gas-liquid multi-phase flow analysis more appropriately.CD, group = fgroupcd (CD)The group is the coefficient of fluid drag for bubbles.Fgroup = 1 / α） By extending n (n = 1.5 to 3)Gas liquid multiphase flow analysis method for gas phase multiphase flow analysis in bubble columnUsing fcluster (≦ 1), which is the rate of decrease in fluid resistance due to bubble clustering by clustering bubbles.Expansion of the fluid drag model for bubble groups with CD, group = fcluster fgroupcd and expansion stepBubble volume occupancy rate α As a function only dependent onFcluster = f α） Assuming a step (1) andExperimental data α） Approximate approximation and.Diagram
