THE PREDICTION OF THE TURBULENT FLOWS IN A TRANSONIC COMPRESSOR ROTOR USING CFD TECHNIQUE

摘要：

This paper describes an accurate and robust methodology for solving the 3D steady/unsteady turbulent flows in compressors. The numerical methods are based on the finite volume scheme with the following new features: (1) a MUSCL interpolation method suitable for non-smooth grids, (2) a robust scheme for evaluating the inviscid fluxes based on the rotated Riemann solver, and (3) a simple procedure for computing the nearest distance to the wall. The turbulence models adopted in the present paper are the two-equation k-ω model and two-equation k-g model. The numerical methodology is validated by solving transonic flows in NASA rotor 37.Detailed comparisons between numerical results and the experimental data are made under the design speed condition to assess the overall quality the numerical solution. The predicted total pressure ratio and adiabatic efficiency agree fairly well with the experimental results.
