Function Modelica.​Fluid.​Dissipation.​HeatTransfer.​General.​kc_approxForcedConvection
Mean convective heat transfer coefficient for forced convection | approximation | turbulent regime | hydrodynamically developed fluid flow

Information

Approximate calculation of the mean convective heat transfer coefficient kc for forced convection with a fully developed fluid flow in a turbulent regime.

A detailed documentation for this convective heat transfer calculation can be found in its underlying function kc_approxForcedConvection_KC . Note that additionally a failure status is observed in this function to check if the intended boundary conditions are fulfilled. See more information .
