modelSplitterRatio
Splits a flow into two subflows with prescribed ratio
Extends from ThermofluidStream.Utilities.DropOfCommonsPlus.
Information
Splitter, that uses a directly set split ratio. In order to have stationary r that goes to zero, a pressure difference between outlet A and B is calculated, that is applied to one of the outlets, until r->0.
The idear builds on the splitter with an enforeced regime of Zimmer Real-Time Simulation of an Aircraft Electric Driven Environmental Control System for Virtual Testing Purposes Sec 3.4
