 note = {The curvature of the wall along the flow direction gives the fluid particles the centripetal force caused by the pressure gradients, which is essential to make the complicated secondary flow such as the Goertler vortices. In spite of several experimental and numerical researches for the incompressible curved flows, the mechanism causes the secondary flow pattern is not clearly explained. Analyzing the results obtained by direct numerical simulations of the compressible viscous flow in the curved duct for the Dean number Dn = 271, we demonstrate that flow helicity distributions signify the secondary flow well and that the acceleration differences between viscous and inviscid flows are essential to specify the area where the curvature effect of the wall governs the fluid particle motion. Finally, we indicate the generalized inflection points of the simulated flow velocity profiles., 資料番号: AA0049212018, レポート番号: JAXA-SP-05-017},
