摘要: This paper describes a new computational tool developed for the analysis of two or three dimensional, viscous inviscid turbomachinery flutter and forced response problems. Time harmonic results are obtained by linearizing underlying steady flow numerical algorithm, including k-ω turbulence model. Solutions via explicit time marching, with multigrid, on multiblock grids. We present that focus role linearization terms model in accurate computation linearized unsteady flows.
