modelNumberOfBeams

Extends from Modelica.Icons.Example (Icon for runnable examples).

Information

This model validates the scaling of the heat tranfer and pressure drop for nBeams > 1.

It uses two instances of IBPSA.Fluid.HeatExchangers.ActiveBeams.CoolingAndHeating, one with nBeams = 1 and one with nBeams = 10.
