Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)), Sagamihara, Kanagawa Japan, Electromagnetic flow control was simulated using magnetohydrodynamic equations to clarify the electromagnetic efects measured in an arcjet flow with a strong Hall parameter which is of order several tens. The result showed that the combined effect of the Hall effect and an insulative boundary in the flow activates the electromagnetic flow control: an ideal uniform ionized flow without any insulative boundary in the flow was found to be unsuitable to investigate the electromagnetic flow control experimentally. In addition, an arcjet plume with a strong Hall effect and ion slip was solved instead of using the artificial insulative plume boundary. The result showed that the shock standoff increases due to the activated Hall electric field and circumferential current whose values are identical to that in the flow with the artificial insulative boundary. Consequently, these results verified the supposition that the non-unifomity in the radical direction is required to activate the electromagnetic control in a flow with a strong Hall efect and ion slip., 資料番号: AA0064729017}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)}, title = {アーク気流中での電磁流れ制御の数値計算}, volume = {平成20年度}, year = {2009} }
