On the effects of free-stream turbulence on axisymmetric disc wakes

E Rind, IP Castro - Experiments in fluids, 2012 - Springer
Wind tunnel experiments have been used to study the effects of free-stream turbulence on
the axisymmetric wake behind a disc. The disc and its wake were introduced to various …

Effect of external turbulence on the evolution of a wake in stratified and unstratified environments

A Pal, S Sarkar - Journal of Fluid Mechanics, 2015 - cambridge.org
Direct numerical simulations are performed to study the evolution of a towed stratified wake
subject to external turbulence in the background. A field of isotropic turbulence is combined …

Direct numerical simulation of axisymmetric wakes embedded in turbulence

E Rind, IP Castro - Journal of Fluid Mechanics, 2012 - cambridge.org
Direct numerical simulation has been used to study the effects of external turbulence on
axisymmetric wakes. In the absence of such turbulence, the time-develo** axially …

[BOK][B] Dynamics of stratified flow past a sphere: simulations using temporal, spatial and body inclusive numerical models

A Pal - 2016 - search.proquest.com
Wakes of bluff bodies in a stratified environment are common in oceanic and atmospheric
flows. Some examples are marine swimmers, underwater submersibles and flow over …

Far axisymmetric wakes in turbulent streams

E Rind, JA Redford, IP Castro - Sixth International Symposium …, 2009 - dl.begellhouse.com
ABSTRACT A time develo** far axisymmetric wake at moderate Reynolds numbers (Re=
O (10 4)) has been simulated without a generating body. When the wake achieved its self …
