谁能帮我解释解释这个HTRI报告，多谢！？ 回复 1# nhd83 对你的设计没有影响。程序应该已经按微分法进行了物性计算。the 2 types of flash methods available for generating physical properties are integral and differential. this field has no effect on single-phase fluids. ?integral this method assumes that vapor and liquid portions of a two-phase fluid are well mixed and in thermal and chemical equilibrium. that is, the composition flashed at each temperature is the same as the specified feed composition. ?differential this method assumes that vapor and liquid portions of a two-phase fluid separate. that is, for a hot fluid (condensing), the composition flashed at each temperature has the liquid portion from the previous flash removed. for a cold fluid (boiling), the composition flashed at each temperature has the vapor portion from the previous flash removed. consider using differential flash in cases of multi-tubepass tubeside condensation when hot fluid separates in the header and of horizontal shellside condensation in gravity-controlled flow.查看更多
