Stochastic modelling and feedback control of bistability in a turbulent bluff body wake

RD Brackston, JMG De La Cruz, A Wynn… - Journal of Fluid …, 2016 - cambridge.org
A specific feature of three-dimensional bluff body wakes, flow bistability, is a subject of
particular recent interest. This feature consists of a random flip** of the wake between two …

Coriolis effect and the attachment of the leading edge vortex

T Jardin - Journal of Fluid Mechanics, 2017 - cambridge.org
The role of the Coriolis effect on the attachment of the leading edge vortex (LEV) is
investigated. Toward that end, the Navier–Stokes equations are solved in the non-inertial …

Diffusive dynamics and stochastic models of turbulent axisymmetric wakes

G Rigas, AS Morgans, RD Brackston… - Journal of Fluid …, 2015 - cambridge.org
A modelling methodology to reproduce the experimental measurements of a turbulent flow
in the presence of symmetry is presented. The flow is a three-dimensional wake generated …

Spanwise gradients in flow speed help stabilize leading-edge vortices on revolving wings

T Jardin, L David - Physical Review E, 2014 - APS
While a leading-edge vortex on an infinite translating wing is shed after a short distance of
travel, its counterpart on a finite span revolving insect wing or maple seed membrane …
