Yonago Convention Center BiG SHiP), Yonago, Tottori Japan, The authors have examined the influence of an induced magnetic field on the MHD flow control by means of two-dimensional numerical simulation. The Hall effect and the ion slip effect are ignored in order to readily understand of influence of the induced magnetic field. The freestream flow is treated as a calorically perfect gas, and the electrical conductivity in the shock layer is assumed to be constant of 10, 100, or 1000 S/m. The magnetic Reynolds number is smaller than unity in the case of the electrical conductivity of 10 S/m. The magnetic Reynolds number, on the other hand, is larger than unity in the case of the electrical conductivity of 1000 S/m. The numerical result has shown that the induced magnetic field weakens the external magnetic field in most of the shock layer. The numerical results have also suggested that the strength of induced magnetic field increases with the electrical conductivity in the shock layer. The induced magnetic field has a substantially negative influence on the usefulness of the MHD flow control when the electrical conductivity takes a large value such as 1000 S/m. The induced magnetic field, however, enhances the total magnetic field in a certain region within the shock layer. The wall heat flux near the region becomes lower than the one in the case of neglecting the induced magnetic field., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0064967024, レポート番号: JAXA-SP-10-012}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {誘導磁場を考慮したMHD Flow Control の2 次元電磁流体解析}, volume = {JAXA-SP-10-012}, year = {2011} }
