Newbie seeking advice: Calculation of heat exchange area for steel-aluminum composite fin heat exchangers
Thread Content
Conditions: Steel-aluminum composite finned tube heat exchanger, with superheated steam as the heat transfer medium used to heat air. Question: How to calculate the overall heat transfer coefficient K, the external heat transfer coefficient ao, and the internal heat transfer coefficient ai? PS: Those who haven’t studied chemical engineering are completely confused; the formulas found in the research materials are varied and it’s hard to know where to start. Thank you

You want me to do the calculations by hand, but I’d be stuck without any tools for that. Software can be used for such calculations; if you need it, just provide me with the relevant details and I can help you work it out
I am very grateful for the kindness of the two people above. Finally, I contacted the design firm, had a discussion, and the issue was resolved.
