Strength calculation of heat exchangers
Thread Content
For a double-pass fixed-tube-sheet heat exchanger where the baffle grooves are not located at the center of the tube sheet, can SW6 be used for calculations?
Yes, just enter the area of the partition groove
It’s completely possible; the area of the partition groove can be calculated based on actual conditions
The calculation for partition grooves can be found at http://bbs.hcbbs.com/viewthread.php?tid=220000&highlight=%B8%F4%B0%E5%B2%DB
Dual-pipe designs rarely become eccentric; I’m not sure why
Perhaps the volume decreases after cooling, which leads to eccentricity.
It can be calculated using SW6; I’ve never encountered any eccentricity though, haha
When using sw6 for calculations, the key factor is whether the value of k is greater than or less than 1, and whether it’s necessary to use the 4732 module~~~
I’m the original poster; first of all, thanks to everyone for their answers! I remember that the partition is not at the center (or the center of the tube sheet does not coincide with the center of the tube bank), and the way stress is applied to the tube sheet is different from what is calculated in SW6; therefore, analytical calculations are required. I heard this from someone many years ago, and I’m not sure if it’s true; now that I’ve encountered it, I’d like to verify it. Could everyone please state the basis? Thank you!
The original poster needs to use SW6 to do the calculations themselves – ^_^ After all, on SW6, since the partition slots aren’t in the middle, it should still be possible to carry out the calculations; all that’s needed is to enter the area of the partition slots!
The partition grooves are usually in the middle; I’ve never seen any that are eccentric. They should be on SW6 – it can be calculated
For the tube sheet, you can just calculate it by hand – is it really necessary to use those crappy chemical engineering software programs?
