.ThermofluidStream.Boundaries.PhaseSeparator .ThermofluidStream.Boundaries.PhaseSeparatorThis Volume is the parent class for Accumulator and Receiver models that separate the two phases and are able to output gas, liquid or two-phase medium, depending on its liquid level and the height of the outlet.
Since there is no formula to compute density_derp_h for this volume, an upper bound has to be set in the parameter density_derp_h_set. Alternativeley the derivative can be taken from the media model for all the media that implement the corresponding formula by setting density_derp_h_from_media=true (default:false).
