Seeking advice on heat exchanger simulation issues
Thread Content
I would like to ask the experts here: I encountered the following problem while using HeatX for simulations. I hope the experts can provide some guidance. Thank you! Block: B4 Model: HEATX * WARNING: THE CALCULATED DELTA-P VALUE FOR THE TUBES IS GREATER THAN THE MAXIMUM ALLOWABLE DELTA-P. THIS IS THE MAXIMUM DELTA-P VALUE USED IN THE CALCULATIONS
In other words, the calculated pressure drop within the pipes must be greater than the maximum allowable value; it is recommended that the person in question adjust the number of pipes and the flow velocity within them, as these two factors have a significant impact on the pressure drop
2# chichy, the explanation given above is very accurate; thank you. Additionally, when I am performing convergence simulations for heat exchangers using tearing flow, I keep encountering the following issue: adjusting the initial values of the tearing flow doesn’t help. I have tried both the Broyden and Wegstein convergence methods, but neither works. I’m not sure why, and I would appreciate your advice on this matter.
