摘要: The effect of a moderate adverse pressure gradient on the interaction between single streamwise vortex and turbulent boundary layer is investigated experimentally. Quantitative characterization properties based measurements mean cross-flow velocity components attained. Growth core observed, followed by flattening shape which occurs when radius becomes comparable to distance center from surface. causes an increase in rate growth and, therefore, stronger distortion shape. Turbulence are even more strongly disturbed than constant pressure.
