With VKI-CT2 turbine blade as the test model, numerical results are compared with experimented data and shows the existence of separation-transition bubble and the interaction of shock with turbulent boundary layer flow. The governing Navier-Stokes equations are solved by an improved numerical method that uses an upwind flux-difference split scheme for spatial descretization and an explicit optimally smoothing multi-stage scheme for time integration. Turbulent stresses are approximated by modifying Baldwin-Lomax algebraic, k-ε, R-k-ε and RNG k-ε turbulence models. According to the results of this research, this analyzer can indeed effectively modulate and simulate the aerodynamic characteristic of the transonic turbine rotor near the endwall.CFD; Endwall; Separation bubble; Transonic rotors; VortexAerodynamics; Boundary layer flow; Bubbles (in fluids); Computational fluid dynamics; Navier Stokes equations; Numerical analysis; Stress analysis; Transonic flow; Turbomachine blades; Turbulent flow; Transonic rotors; Turbulent stresses; Gas turbinesjournal article2-s2.0-0035686522
