Abstract
A numerical code has been developed based on experiment data, by using Finite Volume Method. Four different turbulence models (one equation model) have been tested; Spalart–Allmaras, Delay Eddy Simulation, Delay Detached Eddy Simulation and Improve Delayed Detached Eddy Simulation. The exit Reynolds number is 2.8 106 and the exit isentropic Mach number is 0.79. The code has been validated with isentropic Mach number around the blade, trailing edge pressure distribution, vortex shedding frequency at S/D=-0.62 and boundary layer profile at a distance equal to one. DDES has shown a good agreement qualitatively and quantitatively with the experiment as compared with others and at region -1<S/D<1, all results show insignificant different.
