Exact solutions for submerged von Kármán point vortex streets cotravelling with a wave on a linear shear current [PDF]
, 2023 New exact solutions are presented to the problem of steadily travelling water waves with vorticity wherein a submerged von Kármán point vortex street cotravels with a wave on a linear shear current. Surface tension and gravity are ignored.

Detailed Wake Structure behind an Elastic Airfoil
Journal of Fluid Science and Technology, 2009 An unsteady flow in a low Reynolds number region attracts attention in recent years. The authors measured vortex flow in the wake of the rigid flat plate, rigid NACA0010, elastic flat plate and elastic NACA0010 with heaving motions and evaluated ...

Modelling of coupled cross-flow/in-line vortex-induced vibrations using double Duffing and van der Pol oscillators [PDF]
, 2012 Many studies have typically applied a linear structural spring–mass–damper oscillator and a van der Pol wake oscillator to model a one-dimensional cross-flow vortex-induced vibration (VIV).

Wake states and frequency selection of a streamwise oscillating cylinder [PDF]
, 2013 This paper presents the results of an in-depth study of the flow past a streamwise oscillating cylinder, examining the impact of varying the amplitude and frequency of the oscillation, and the Reynolds number of the incoming flow.

Mechanism of momentum transportation in the intermediate wake of a heated cylinder
Nihon Kikai Gakkai ronbunshu, 2020 Measurements in the wake of a heated cylinder are made by a thermo-anemometer. The purpose is to make clear the effects of buoyancy of heated cylinder on the mechanism of momentum transportation in the wake.

Short-scale break-up in unsteady interactive layers: Local development of normal pressure gradients and vortex wind-up [PDF]
, 1998 Following the finite-time collapse of an unsteady interacting boundary layer (step 1), shortened length and time scales are examined here in the near-wall dynamics of transitional-turbulent boundary layers or during dynamic stall.

Heat transfer enhancement in natural convective channel flows by vortex streets [PDF]
, 2022 Heat transfer in vertical heated channels is a common means to operate thermodynamic devices like panel radiators for room heating. Reducing the required material amount or increasing the performance leads to positive effects in terms of economical and ...
