Doubts about PRO’s rigorous heat exchanger simulation...
Thread Content
After successfully performing heat transfer simulations of a water-water system shell-and-tube heat exchanger (BEM) using HTFS+, it is desired to use PRO to verify the heat exchanger model rigorously. The following error messages appeared: 2 error(s), 0 warning(s), and 0 message(s) detected: *** error *** Unit 1, ‘e1’ – methods for transport properties are required for shell-side calculations, but they are missing from the thermodynamic method set “nrtl01”. *** error *** Unit 1, ‘e1’ – methods for transport properties are required for tube-side calculations, but they are missing from the thermodynamic method set “nrtl01”. No calculations using a detailed heat exchanger model have been performed before. This error cannot be understood or resolved effectively. I hope those with experience will stop by to offer guidance. . . . . Thank you
Thermodynamic data------Select the thermodynamic method------Modify------Transport Properties------Select transport properties and try again
The results simulated by HTFS+ and PRO are in excellent agreement.
