Channell Pressure Drop and Heat Transfer Model #3958

I am developing a model of a vertical channel with pressure drop and heat transfer behavior. I would like to use the Fluid library but cannot find definition of the inputs for the channel (Modelica.Fluid.Dissipation.PressureLoss.Channel.dp_internalFlowOverall_DP). Following that I would like to add a condensate distribution and drainage model to the channel. This is to support a thesis I am writing.

Are there any examples in Modelica library or outside of it that can be used as a guide?

Regards,
