Tube bundle (Pressure drop and heat transfer)

[PhilOos]

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.

TEMA has a chapter about heat transfer and pressure drop

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
