I am looking for a Nusselt number correlation that will work for a shell & tube heat exchanger in the Re < 3000 region, i.e. extremely laminar flow (for a lab experiment).

 

I've been searching for a while now, but can only find empirical correlations for Re > 3000, and was thus hoping that someone could point me in the right direction.

The Nusselt number for laminar flow in a smooth tube depends on RePr. For small values the Nusselt number is 3.66. One place you can find more information is in the Heat Exchanger Design Handbook.
