Skin friction and pressure: the “footprints” of turbulence

TR Bewley, B Protas - Physica D: Nonlinear Phenomena, 2004 - Elsevier
The problems of exact state reconstruction and approximate state estimation based on wall
information in a wall-bounded incompressible unsteady flow are addressed. It is shown that …

The effect of uniform blowing on the flow past a circular cylinder

L Mathelin, F Bataille, A Lallemand - J. Fluids Eng., 2002 - asmedigitalcollection.asme.org

Investigation into wakes generated by surface piercing periscopes

A Conway - 2017 - figshare.utas.edu.au
For operational purposes, submarines are required to pierce the free surface with masts,
such as periscopes and snorkels. These masts generate a large plume structure which can …

Bluff Body Wake Stability Enhancement by Mean of Non-Isothermal Blowing

L Mathelin, F Bataille - Machine Dynamics Research, 2011 - infona.pl
The influence of blowing or suction from the surface of a porous circular cylinder in crossflow
onto the dynamics of its near wake is numerically studied for flows close to the onset of the …
