functionkc_roundTube
Extends from Modelica.Icons.Function (Icon for functions).
Information
Calculation of the mean convective heat transfer coefficient kc for the air-side heat transfer of heat exchangers with round tubes and several fin geometries. Note that additionally a failure status is observed in this function to check if the intended boundary conditions are fulfilled. See more information .
