WebMar 5, 2024 · Fig. 9.4 Oscillating Von Karman Vortex Street. The frequency ω or f is referred to as the "unsteadiness'' of the system. Generally, the periodic effect is enforced by the boundary conditions or the initial conditions. In other situations, the physics itself instores or forces periodic instability. WebApr 13, 2024 · Subaqueous vortex ripples in equilibrium are characterized by their unique geometry and dimensions. Motivated by the recent direct numerical simulation study of oscillatory turbulent flow over a wavy bottom by Önder & Yuan (J. Fluid Mech., vol. 858, 2024, pp. 264–314), the objective of this study is to further investigate the fluid …
