Higher order structure functions clearly demonstrated experimental errors. The scaling index showed that stratified turbulence was more intermittent than neutral one. Fine-scale coherent vortices were also detected by using conditional averaging in the stably stratified turbulent flow. The coherent vortices were similar to Burgers eddies found in the neutral turbulence fields simulated by DNS. They did not contribute to heat transfer well., 資料番号: AA0032827016, レポート番号: NAL SP-54}, pages = {61--64}, publisher = {航空宇宙技術研究所, National Aerospace Laboratory (NAL)}, title = {温度成層乱流の速度場と温度場の構造}, volume = {54}, year = {2002} }
