Petukhov

fullflow.Petukhov

Petukhov turbulent forced-convection heat transfer coefficient.

Petukhov computes the convective heat transfer coefficient for turbulent internal flow using the Petukhov correlation. The correlation uses the Darcy friction factor and is intended for single-phase turbulent flow.
