我用aspen带的EDR核算换热器，这是什么，求解答

妖迺，sir！~

The required fraction of the surface area for cooling the liquid phase is approximately 15%. However the number of naturally submerged tuber ,caculated balanced  pressure drop modle, is 290,which means that 22% of the surface is submerged by the liquid phase.you can re-run the case with an input value area fraction submerged less than 22% to bring the input and required values of the submerged surface into agreement   这是什么意思

给定的淹没在水中的表面积太大了，调小试试

楼主是在模拟蒸汽加热的换热器或者冷凝器吧？、
提示的意思是 部分换热管浸没在凝液里面了，所以导致换热面积不够

建议你把文件上传让大家分析
