optimal fin height
optimal fin height
(OP)
We have cylindrical tank. It is made of ½" thick carbon steel. It's dimensions are 7' x 20'. We need to install fins (flights) inside tank to facilitate heat transfer. We need to know the optimal fin dimensions for effective heat transfer. The flights would be made of carbon steel. Due to the material inside the cylinder, the flights must be at least ½" thick.
Tank data:
Indirectly heated exterior with air up to 1400 F, velocity 45 feet per second.
What would be an optimal fin height inside the tank to maximize heat transfer?

RE: optimal fin height
On second instance, have you considered rapid oxidation as possible issue for carbon steel in contact with air at that temperature?

Then you can calc how much heat you have to move from the fluid to your heat sink. With this info, you can calculate the fin height as needed. The right fin height will be the one that works for your application.

Doesn't make sense -> As mentioend, Wouldn't you need the fins to be on the "gas" side of the tank, not the liquid side?
