Co-operative Destabilization of a Flat Plate Boundary Layer by a Free Stream Convecting Vortex and Wall Suction/Blowing
The stability of wall bounded shear layer at subcritical Reynolds number disturbed by a freestream convecting vortex and unsteady suction/blowing at the wall was studied. A counterclockwise line vortex was convected parallel ... -
Effect of a Mesh on Boundary Layer Transition Induced by Free-stream Turbulence and an Isolated Roughness Element
(2018-06-23)A high level of free-stream turbulence and surface roughness are known to cause breakdown of an otherwise stable laminar flow. In transition induced by free-stream turbulence, streaks are formed due to the lift-up effect ... -
Experiments on the Late Stages of Boundary Layer Transition
(2018-03-19)In canonical boundary layer transition, a uniform laminar flow perturbed by 2-d T-S waves develops downstream into 3-d waves, which eventually break down with turbulent spots appearing. Previous experimental studies have ... -
Linear Instability Of Laterally Strained Constant Pressure Boundary Layer Flows
(Indian Institute of Science, 2007-03-26)The linear instability of laterally diverging/converging flows is an important aspect towards understanding the laminar-transition process in many viscous flows. In this work the linear instability of constant pressure ... -
A Study On Boundary Layer Transition Induced By Large Freestream Disturbances
(2013-06-12)The initial slow viscous growth of the Tollmein-Schlichting wave in a canonical boundary layer transition is absent in bypass and wake-induced transitions. Although there have been a great deal of studies pertaining to ... -
Transition Zone In Constant Pressure Boundary Layer With Converging Streamlines
(Indian Institute of Science, 2007-04-18)The laminar-turbulent transition in viscous fluid flows is one of the most intriguing problems in fluid dynamics today. In view of the enormous applications it has in a variety of fields such as aircraft design, turbomachinery, ...
