Solver : density based - explisit - unsteady - 2nd order Implicit (the other is default) Viscous model : k-epsilon (default) Material : user defined ( parameters are based on 3 bar water vapor with ideal-gas density) Operating Pressure : 0 Boundary Conditions : inlet stator : pressure inlet : 300000 pascal - turbulent intensity 3.6 % - hydraulic diameter 0.01898 m - temperature 469.4314 K interface stator interface rotor outlet stator : pressure outlet : 128567 pascal - turbulent intensity 3.48 % - hydraulic diameter 0.01898 m - temperature 406.0244 K fluid rotor : Moving mesh - y velocity 68.3296 m/s Solution Controls : relax factor : default courant number 1 - multigrid levels 5 discret : second order
