超音速乱流底面熱伝達の一近似解法-境界層厚さを考慮した場合

Autor: INOUE, Yasutoshi, Robert, H.Page

Publikováno v: 航空宇宙技術研究所報告 = Technical Report of National Aerospace Laboratory TR-497. 497:18

Base heat transfer of a two-dimensional bluff body in supersonic and hypersonic flows is analysed by the component analysis method, paying special attention to the effect of the approaching turbulent boundary layer thickness on the heat transfer rate

Based on the idea that turbulence is the flow phenomena caused by the movement of vortex, the structures of turbulent boundary layer are discussed. The circulation is the most important factor for characterizing the flow structures. The large scale m
