But little is known about the wake structure of a group of cylinders in complicated configurations. This paper presents the first step to this complicated problem. We made a measurement by hot-wire anemometer in a small low-turbulence wind tunnel. The most important process in the wake is the randomization process in the vortex street. We introduced the objective measurement of the wake by comparing line and continuous spectra. It was proved that the downstream cylinder screens the vortex street of the upstream cylinder., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0064575004, レポート番号: JAXA-SP-09-014}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {円柱群後流の構造}, volume = {JAXA-SP-09-014}, year = {2010} }
