Coil-type heat exchanger design: the issue of selecting the heat transfer coefficient value
Thread Content
I would like to design a coiled-tube heat exchanger, with the refrigerant inside the tubes and lubricating oil with a viscosity of 50 mm2/s on the outside of the tubes (natural convection). The specific arrangement is to place the coils on the four walls and bottom of the oil tank, which is filled with lubricating oil. May I ask what the empirical value of the heat transfer coefficient K is in this case? Or are there any recommended design software or books?

As for \"placing the coils on the four walls and bottom of the oil tank,\" it’s not clear what considerations led to the choice of those locations. Do it yourself, and you’ll have enough to eat and wear.
The coils are arranged on the four walls and bottom of the oil tank because a heat source needs to be placed in the middle of the tank. How is it that the trial version of the software you recommended can’t even produce a concise result?
