EDR换热器设计的警告解决办法

警告1.You did not specify the number of crossflow baffles. This has been calculated as 7, the nearest value, given the tube length 3500 mm, endlengths 438.1 mm and 535.85 mm (as input or estimated), and a baffle pitch of 400 mm.
请问这个警告需要处理么?

警告2.The bundle band orientation has 2 pass partition lanes in line with the flow, which may give significant by-passing around the tube regions. Changing the orientation of the bundle would give 1 in-line lane(s) and reduced by-passing.
请问这个警告什么意思,是不是与我设计的4管程有关系,pass layout为Mixed(H)

警告3.This is probably a case where the baffle cuts are not consistently located with respect to tube centres.Revising the cuts on the tube layout diagram may be needed.Otherwise, this problem can usually be avoided if you specify bundle layout symmetry case 1 or 2,For H-banded layouts you may also need to adjust the central pp lane width.
请问这个警告什么意思,这个需要处理么?

警告1:没有定义折流板数量,系统自动帮你算好了,不用管。
警告2:你的H型排管形式会产生明显旁路,如果你要坚持那就忽略。
警告3:貌似是你的折流板切口和排管产生了矛盾,建议尝试修改bundle layout symmetry 和central pp lane width消除警告https://meng.horse/forum.php?mod=image&aid=103698&size=300x300&key=b1392418d0cddfe4&nocache=yes&type=fixnonehttps://meng.horse/forum.php?mod=image&aid=103699&size=300x300&key=3cdcaf22e0a1adc7&nocache=yes&type=fixnone

自己在翻译网站上 翻译一下

定义一下“折流板数”、改变一下折流板的“切割率”试试看

管壳式不太熟悉,进来学习一下!

请问您这个软件好不好安装,有安装包吗?

ectxcqm 发表于 2019-3-13 15:14:03

基本的英文应该都懂些,否则不好理解

t请问这个是换热面积比太大了吗:he ratio 3.66475 of an end space length to the baffle space is larger than normal。Shellside heat transfer and pressuer drop calculations may be less accurate than normal,especially if there is a small number of baffes. Note that the fraction of the overall resistance to heat transfer due to the shellside is 0.007505804.
