Does anyone know where I can find the governing equations on the heat transfer of a horizontal, closed loop system?(adsbygoogle = window.adsbygoogle || []).push({});

e.g. http://www.eere.energy.gov/consumer/images/closed_loop_system_horiz.gif

I've tried searching online, and all I can find is the general overview, no equations

In particular, I know that the Nusselt Number is some function of the Reynolds and Dean Numbers in this case -- what it is exactly I have no idea.

Can anyone recommend any articles, textbooks, anything?!

Thanks
