Tube bundle (Pressure drop and heat transfer)
Tube bundle (Pressure drop and heat transfer)
(OP)
Hi,
I've been trying to find theory to calculate the pressure drop and heat transfer over a bank of tubes. I want to generate geometry specific friction and Colburn j factor charts (as in Kays & London).
The best source I have is the VDI Wärmeatlas but I don't understand German. Is there someone that knows of a good source?
Regards
Philip

Both discuss exchanger tube x-flows... & both are in English.

RE: Tube bundle (Pressure drop and heat transfer)
There you will find the chart to calculate the Mean Temperature Difference MTD.
MTD=GTTD-LTTD/Log e GTTD/LTTD
GTTD=Greater Terminal Temperature Difference
LTTD=Lesser Terminal Temperature Difference
