Heat Transfer Coefficients

[iken]

I have done a search on previous threads, and cant seem to find an answer to this (although I believe it would have been asked/answered previously).

Can anybody advise the best (most comprehensive) text book, of reference tables for the heat transfer coefficient for tubes (copper and steel) in shell & tube heat exchangers.

This would be water to water type. I realise there are "ranges" given, but I assume there is/has been experiments done in the past, with the results being published for various flows etc.

Any help would be appreciated.

Thanks

Heat transfer college text books should have those values readily availavble.

When performing the heat transfer calcs for an exchanger, you will need to calculate the overall heat transfer coefficient, which is based on fluid types, velocities, conductivities, viscocities, etc. You should review GPSA Manual Section 9 for how to obtain film coefficients at different flow rates and calculate the overall heat transfer coefficients based on inside, outside, & metal coefficients.

Hi Iken,

The most comprehensive book is "Heat Exchangers Design Handbook". see

http://www.begellhouse.com

for details.

Almost all commercial softwares (b-jac, tasc) for hX design are based on it.

see also: process heat transfer by G. Hewitt.

Thanks for the suggested books, I will try and track these down.

Cheers

Go to Perry's "Chemical Engineers Handbook." There you will find methods for sizing shell and tube heat exchangers, and you will find many references.

Also, on the internet, look for HTRI (Heat Transfer Research Institute). I don't know if they still exist, but as recently as 10 years ago, they performed computer sizing calculations, for a fee of course.
