Numerical Simulation on Vortex Shedding from a Hydrofoil in Steady Flow [PDF]
Journal of Marine Science and Engineering, 2020 This paper presents a numerical modeling procedure for the idealization of vortex shedding effects in the wake flow field of a NACA0009 hydrofoil. During the simulation, the lift and drag acting on the hydrofoil were monitored, and the vortex-shedding ...

Research on smoke simulation with vortex shedding. [PDF]
PLoS One, 2022 The Lagrangian vortex method has the advantage of producing highly detailed simulations of fluids such as turbulent smoke. However, this method has two problems: the construction of the velocity field from the vorticity field is inefficient, and handling the boundary condition is difficult. We present a pure Lagrangian vortex method, including a nested

Phenomenon of Alfvénic Vortex Shedding [PDF]
Physical Review Letters, 2010 Generation of Alfvénic (magnetohydrodynamic) vortices by the interaction of compressible plasma flows with magnetic-field-aligned blunt obstacles is modeled in terms of magnetohydrodynamics. It is found that periodic shedding of vortices with opposite vorticity is a robust feature of the interaction in a broad range of plasma parameters: for plasma ...

A numerical study of an inline oscillating cylinder in a free stream [PDF]
, 2011 Simulations of a cylinder undergoing externally controlled sinusoidal oscillations in the free stream direction have been performed. The frequency of oscillation was kept equal to the vortex shedding frequency from a fixed cylinder, while the amplitude ...

Vortex evolution near the Coanda surface of a circulation control airfoil with pulsed actuation
AIP Advances, 2022 A special vortex evolution process was found near the Coanda surface for circulation control airfoil with pulsed actuation. For the jet-on process, two successive shedding vortices from the lower lip edge and the separation vortex on the Coanda surface ...

Vortex streets to the lee of Madeira in a kilometre-resolution regional climate model [PDF]
Weather and Climate Dynamics, 2023 Atmospheric vortex streets are a widely studied dynamical effect of isolated mountainous islands. Observational evidence comes from case studies and satellite imagery, but the climatology and annual cycle of vortex shedding are often poorly understood ...
