kc_turbulent

Mean heat transfer coefficient of straight pipe | hydrodynamically developed turbulent flow regime | pressure loss dependence

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Calculation of mean convective heat transfer coefficient kc of a straight pipe for a hydrodynamically developed turbulent fluid flow at uniform wall temperature or uniform heat flux with neglecting or considering of pressure loss influence. Note that additionally a failure status is observed in this function to check if the intended boundary conditions are fulfilled. See more information .
