ASPEN 回归参数2? 各位高手请指点,我采用NRTL和PR方程回归 R134A-DMF的相平衡参数均可行,但原文章(数据发表的文章)是采用NRTL-PR来关联数据的,我在ASPEN中也采用了NRTL-PR来关联,其得到结果都为: *** SEVERE ERROR WHILE EXECUTING DRS CASE: "NRTL-PR" FLASH RESULTS ARE WITHIN TOLERANCE, BUT MAY BE UNSATISFACTORY BECAUSE EXTRAPOLATED EOS VAPOR VOLUME ROOT WAS USED FOR PROPERTY CALCULATIONS. *** SEVERE ERROR WHILE EXECUTING DRS CASE: "NRTL-PR" FLASH RESULTS ARE WITHIN TOLERANCE, BUT MAY BE UNSATISFACTORY BECAUSE EXTRAPOLATED EOS VAPOR VOLUME ROOT WAS USED FOR PROPERTY CALCULATIONS. *** SEVERE ERROR WHILE EXECUTING DRS CASE: "NRTL-PR" FLASH RESULTS ARE WITHIN TOLERANCE, BUT MAY BE UNSATISFACTORY BECAUSE EXTRAPOLATED EOS VAPOR VOLUME ROOT WAS USED FOR PROPERTY CALCULATIONS. 不知哪位高手能帮解决。谢谢 BPK文件见附件!查看更多0个回答 . 4人已关注
