Improve initialization of ULg pipe #61

Closed bramvdh91 closed 7 years ago

bramvdh91 commented 7 years ago

Use 17°C as initial temperature instead of 20.

@marcusfuchs I see that the initialization is now a parameter (initial enthalpy at in- and outlet) in PipeLosslessPlugFlow. Would you say it is better to make the temperature the initialization input here or are you using this parameter somewhere else already? If not, I would propose to change the enthalpy by the temperature (bit more relatable) and calculate the enthalpy inside the component.

@k-sartor Added initialization, yielding very good results! validationpipeulg

Only added initialization for PipeHeatLossMod, see #63

Ok. I will check the experimental data with the last model.
