The simplest method is a conditional measurement using an X-probe. Various turbulence fields at R(sub lambda) = 19 to 2,300 could be measured by this method and the Reynolds number dependences of the characteristics of the fine-scale coherent vortex were obtained. But, such data showed an error caused by the third velocity component unmeasured. So employed was a double-X probe that can measure three components of instantaneous velocity fluctuation. The resultant data showed that the fine-scale coherent vortex was slightly different, from the Burgers' vortex. Also examined was the array of X-probe that can measure instantaneous 2-D velocity profiles. Though it is in progress of such experiments, the primary results showed the validity of the conditional measurement using single X-probe., 資料番号: AA0047776006, レポート番号: JAXA-SP-04-002}, pages = {17--20}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {乱流中の微細秩序渦を実験的に検出する試み}, volume = {JAXA-SP-04-002}, year = {2005} }
