It is a steady symmetric flow that is realized at small Reynolds numbers, but the flow becomes unstable above a critical Reynolds numbers. It has been believed that the resultant flow due to the instability is always oscillatory. However, we found a steady asymmetric flow as well as the oscillatory flow arising from the instability in a region of the gap width between the two cylinders. We evaluated the critical Reynolds number and clarified the region of the gap width in which the steady asymmetric flow is realized., 資料番号: AA0063156019, レポート番号: JAXA-SP-06-013}, pages = {65--68}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {2円柱を横切る流れの不安定性と遷移}, volume = {JAXA-SP-06-013}, year = {2007} }
