Heat exchanger design calculation
Thread Content
I was wondering if there is anyone familiar with the sectional design calculations for shell-and-tube heat exchangers, or if anyone can recommend useful materials. Segmented calculation is an algorithm that divides the shell and tube sides of a heat exchanger into several sections, calculates the fluid parameters for each section separately, and then combines these results to determine the average heat transfer coefficient, outlet temperature, and total pressure drop. Thank you
This should be applied to phase change calculations, such as condensation. It is divided into a cooling stage, a condensation stage, and a supercooling stage; the heat exchange area can be calculated based on the heat load of each stage. When performing the calculations, it’s sufficient to consider the average temperature difference. The inlet and outlet temperatures vary for each stage, and the temperatures of the fluids on both sides are determined through heat balance calculations
Non-phase transitions can also be calculated using this method; the calculation model in HTRI is of this type. However, they use a flow path analysis approach. I’m looking for a calculation model in this area right now
Oh, then I don’t know how to find the model; manual calculation should work following that approach.
If it is a shell-and-tube heat exchanger, refer to the book \"Principles of Chemical Engineering\" by Chen Minheng. There are detailed examples; if the process is slightly different, one can refer to the analysis in the early sections of the book. Very good and detailed!
