Multitube Heat Exchanger Design

Multitube Heat Exchanger Design

(OP)
Can anyone help me in finding the recommended correlations for the heat transfer coefficient and deltaP for the shell side in a multitube (hairpin) exchanger?

Is there any table to determine the number tubes that fit in these shells, like in a normal Shell and tube exchanger?

RE: Multitube Heat Exchanger Design

Hi ChemE2912

Kern has a chapter on extended surfaces. He has an example of a multi-tube starting on page 535.

Process Heat Transfer by Hewitt,et al has the equations for the equivalent diameter of a multi-tube bundle on page 260.

Heat Exchanger Design Handbook (2002) has a rudimentary friction factor curve that includes finned tubes. That is on page 3.3.12-4

Good Luck

RE: Multitube Heat Exchanger Design

Perry VI table 11-3 gives the number of tubes for TEMA U for various shell and tube diameters as well as for 2-4-6 tube passes, type and size of tube pitches. Chapter 10 is helpful in thermal design considerations.
