Combinations of time marching scheme and convection scheme for all-speed CFD were tested in order to reduce computational cost to predict hot gas ingestion through rim seal of high pressure turbine. Preconditioning alternating direction implicit symmetric Gauss Seidel (pADI-SGS) scheme and SLAU were selected in the present simulation based on screening simulation on simplified axisymmetric geometry. Three-dimensional simulation showed that the combination of pADI-SGS and SLAU was more efficient from 4 to 10 times than classical scheme., 資料番号: PA1520025000}, pages = {361--366}, title = {高圧タービンのリムシール部における主流巻き込み予測のための数値解析手法}, volume = {42}, year = {2014} }
