The spherical Couette flow between two concentric spheres with the inner one rotating is computed. The spiral Taylor-Goertler (TG) vortex flow was simulated, and a comparison of the numerical solutions with the available experimental measurements was also made. It is demonstrated that the three dimensional spiral TG vortices in the spherical Couette flow are well simulated., 資料番号: AA0001655017, レポート番号: NAL SP-40}, pages = {67--70}, publisher = {航空宇宙技術研究所, National Aerospace Laboratory (NAL)}, title = {Direct numerical simulation on spiral Taylor-Gortler vortices in the spherical Couette flow}, volume = {40}, year = {1999} }
