Effect of uniform blowing or suction on hypersonic spatially developing turbulent boundary layers

查看参考文献8篇

文摘 Over the past decades, the reduction of drag has attracted considerable attention for its potential applications in engineering [1-3]. Direct numerical simulations (DNSs) provide accurate data that can be used to study the underlying physics of drag reduction. In a recent DNS [4] of an incompressible spatially developing turbulent boundary layer with uniform blowing or suction applied on the wall, the drag reduction mechanism was quantitatively explained by the Fukagata, Iwamoto and Kasagi (FIK) identity [5]. Compared with incompressible flows, far fewer studies have been reported for high-speed (hypersonic) flows. Therefore, the purpose of this study is to investigate the effects of uniform blowing and uniform suction on the skin-friction in hypersonic turbulent boundary layers.
