How to calculate when the heat exchanger tube sheet is square
Thread Content
Due to structural reasons, the heat exchanger tube sheet must be designed as square-shaped. How is this calculated, and what are the relevant standards? Thank you!
Designing it in a circular shape and using the diameter of the circle as the side length of the square tube sheet is a waste of material, hehe
The most reasonable way to calculate square tube sheets is by using analytical methods, based on the third strength theory. It is best to use ANSYS for analysis when possible. You can refer to the equivalent diameter values for square tube sheets specified in shipbuilding standards, but our checks have shown that these values differ from those obtained through ANSYS analysis; they are actually smaller than the results produced by ANSYS
