Effect of Controlled Resonant Interactions and Mode Detuning on Turbulent Transition in Boundary Lay higher harmonic modes including (3/2α, ±.), (5/2α, ±2.), (α,±2.) and (0, ±2.). Contrasted with these are nonlinear interactions produced by initial nonfundamental/subharmonic modes. Comparisons point to the role of detuned modes as a mechanism for energy saturation and spectral filling associated with laminar-to-turbulent transition.作者: 舔食 時(shí)間: 2025-3-22 04:29 作者: Halfhearted 時(shí)間: 2025-3-22 08:31 作者: Jubilation 時(shí)間: 2025-3-22 09:40 作者: genuine 時(shí)間: 2025-3-22 15:01

Role of Transients in Boundary Layer Instability and Transitiond to lead to the formation of internal shear layers. Inflectional instability and subsequent breakdown of such shear layers may be the dominant cause of transition in shear flows subjected to strong external disturbances, a mechanism that may be operative also at subcritical Reynolds numbers.作者: insomnia 時(shí)間: 2025-3-23 09:34 作者: Eclampsia 時(shí)間: 2025-3-23 13:27
