단단 축류압축기 유동해석에 대한 k-w 난류모델의 응용
Application of k-w turbulence model to the analysis of the flow through a single stage axial-flow compressor
초록
A numerical study based on the three-dimensional thin-layer Navier-Stokes solver is carried out to analyze the flowfield through a single stage transonic compressor. Explicit four-step Runge-Kutta scheme with spatially variable time step and implicit residual smoothing is used. The governing equations are discretized with exploit finite difference method. Mixed-out average method is used at the interface between rotor and stator. And, an artificial dissipation model is used to assure the stability of solution. The results with k-
