modelGas_pT
Gas vapor model with p, T and xi as independent variables
Extends from TILMedia.BaseClasses.PartialGas_pT (Gas vapor model with p, T and xi as independent variables).
Information
The gas model Gas_pT calculates the thermopyhsical property data with given inputs: pressure (p), temperature (T), mass fraction (xi) and the parameter gasType.
The interface and the way of using, is demonstrated in the Testers -> TestGas.
