Towards passive station holding of autonomous underwater vehicles inspired by fish behaviour in unsteady flows [PDF]
, 2015 Some species of fish are able to alter their mode of swimming to interact with naturally produced vortices; the use of these gaits reduces the energy expended by the fish.

Flexible patchy vegetation in a meandering bend: Effect on main flow and dispersion processes
Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.The presence of finite flexible and submerged vegetation patches in bends alters the typical curvature‐induced circulation motion and the streamwise velocity distribution, determining a fragmented flow patternThe lateral dispersion and the mass exchanges are strongly influenced by the vegetated patches and turbulent structures forming in patch‐adjacent

Von K\'arm\'an vortex street in a Bose-Einstein condensate
, 2010 Vortex shedding from an obstacle potential moving in a Bose-Einstein condensate is investigated. Long-lived alternately aligned vortex pairs are found to form in the wake, as for the von K\'arm\'an vortex street in classical viscous fluids.

International Journal for Numerical Methods in Fluids, Volume 98, Issue 3, Page 321-347, March 2026.A hybrid RANS‐LES turbulence model adapted for the Moving Particle Semi‐implicit method is employed to investigate a turbulent free surface flow. A method based on the cell‐linked list is proposed to speed up the nearest wall search for the turbulence model.

Proper orthogonal decomposition analysis of vortex shedding behind a rotating circular cylinder
EPJ Web of Conferences, 2016 Turbulence studies were made in the wake of a rotating circular cylinder in a uniform free stream with the objective of describing the patterns of the vortex shedding up to suppression of the periodic vortex street at high velocity ratios, λ. The results

Reduced-order modeling of transonic flows around an airfoil submitted to small deformations [PDF]
, 2011 A reduced-order model (ROM) is developed for the prediction of unsteady transonic flows past an airfoil submitted to small deformations, at moderate Reynolds number.

Vortex Line Density in a Superfluid Turbulent Wake in the Zero Temperature Limit
Annalen der Physik, Volume 538, Issue 1, January 2026.The quasiclassical conjecture for quantum turbulence in a pure superfluid straightforwardly leads to the definition of the superfluid Reynolds number, Res=ud/κ$Re_s=ud/\kappa$, and suggests that the effective quantum viscosity should be of the order of the circulation quantum κ$\kappa$.

Resources, 2023 This study explores the feasibility of using an oscillating plate downstream of a cylindrical body to produce mechanical energy from a Von Kármán vortex street under sub-critical flow conditions (Re = 72,500). The study aims to quantify the impact of the
