Broad areas of Research:
Deterministic & stochastic treatment of nonlinear fluid- structure-interaction and fluid flow problems
Unsteady fluid dynamics (of moving bodies)
(details of research topics)
The accompanying frame shows a periodically moving airfoil generating aperiodic wake patterns which is in fact dynamical chaos. The instability shown here takes the well known quasi-periodic route. Other routes have alse been found in our studies with flapping wings, such as period-doubling and intermittency routes. The dynamics becomes much more interesting with more complex transitional behaviour as the structure becomes flexible and the coupled fluid-structure interaction dictate the unsteady flow-field. See our recent publications for more details.
Sunetra Sarkar obtained her PhD from Indian Institute of Science, Bangalore, India and did her post-doctoral studies from Technical University of Delft, Netherlands. (see Sunetra Sarkar's professional background).
Her research interests lie in the field of dynamics of fluid structure interaction and unsteady flows. Over the years, a variety of problems related to this field have been studied, mainly through computational modelling of varied fidelities, and recently, using experimental techniques as well. One of the main focal points has been development of efficient numerical solvers, as the problems encountered were often nonlinear and needed to be characterized in a time accurate manner over large windows of time. These investigations have led to the resolution of the underlying bifurcations of the coupled systems as well as the flow-field vortex patterns. Novel flow-field wake modes and new bifurcation routes to fluid-elastic instabilities were reported which are of considerable interest to the community.
