Numerical solution of inviscid transonic 2D flow in a nozle using various non-ideal equations of state
Original language description
The system of Euler equations, which describes an inviscid fluid flow, must be closed with some thermodynamic relations known as an equation of state. The simplest example of it is the perfect gas model, which is frequently used in numerical codes. However, in some regions where the compressibility factor differs significantly from one, more sophisticated models should be applied to avoid errors. The results achieved using the perfect gas, van der Waals, Redlich-Kwong-Augier and one-coefficient virial equation of state for steam are compared with the chosen simpler reference solution based on the equation of state provided by IAPWS-95. All these models were implemented into in-house code based on the finite volume method in 2D along with AUSM+ flux andwere tested for steady transonic flow at off-design conditions for convergent-divergent Barschdorff nozzle (shock wave in the divergent part).
