I have calculated the power losses of the system and the inlet and outlet temperatures for both air and waterside. Using LMTD method, the overall heat transfer coefficient of the CHE was found.
I am unable to proceed further, mainly because I could not find any reports on the heat exchanger(it is similar to a car radiator but smaller form factor) I am working with. How do I find the heat transfer coefficient for the air and water side?
I am unsure of which relations to use from Kays and London book on Compact Heat exchangers (CHE).
Any suggestion on software/books/reports on finding the heat transfer coefficient of this type of heat exchanger would be greatly helpful.
Thanking you in advance.
Measure the heat transfer. Vary the inputs. Switch to water on the outside and air on the inside. Use Reynolds Analogy, St=f/2. Kays & London is an excellent reference. So is TEMA and HEI and various ASME documents.
