Ask the Expert - Modeling Reacting Flows using Real Gas Properties
Thermodynamic properties calculated using Ideal gas law vary considerably at high pressures (P›Pc) and low temperatures (T›Tc) from the actual properties of fluids. Real gas equation of state characterize fluid properties more accurately and need to be used to calculate thermodynamic properties at these pressure and temperature conditions which prevail, for example, in rocket engine combustors or fuel injectors for IC engines. In ANSYS CFD several equation of state (Redlich-Kwong, Soave-Redlich-Kwong, Peng-Robinson and Aungier-Redlich-Kwong) are available to model real gas properties. This webinar focuses on simulation approaches involving real gas effects in ANSYS R13 . Validation examples including reacting and non reacting flows will be discussed.
