Test case for Flow1D2ph
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
The model is designed to test the component Flow1D2phDB (fluid side of a heat exchanger, finite volumes, two-phase flow, heat transfer computation) with a prescribed external heat flux, for debugging purposes. The heat transfer coefficient on the wall connector should be a continuous function.
Simulation Interval = [0...300] sec
Integration Algorithm = DASSL
Algorithm Tolerance = 1e-7
