- J011021 Large-Scale Numerical Analysis of Rotating Stall Inception in a Multistage Axial Compressor
抄録
Large-scale detached eddy simulations (DES) have been conducted on the K computer, in order to elucidate the flow mechanism of the rotating stall inception in a multi-stage axial compressor for an actual gas turbine. The detached eddy simulation approach is based on k-ω two-equation turbulence model. The present DES program parallelized with MPI has high speed-up performance. To investigate complex vortical flow phenomena at near-stall conditions, vortex structures are identified by the critical point theory, and limiting streamlines are visualized by a line integral convolution (LIC).
