Role of Non-Wave-Like Disturbances in Transitionage, a linear viscous stage, and a nonlinear stage. The analytical solutions show the appearance of convected portions, with constant, and logarithmically increasing amplitudes, on which regions of high streamwise and spanwise shear may arise. Also, there is formed a streak of low or high-speed flow increasing in length in proportion to time.作者: 裁決 時(shí)間: 2025-3-22 13:53 作者: 軍火 時(shí)間: 2025-3-22 20:49 作者: humectant 時(shí)間: 2025-3-22 22:00
