Recent Results and Papers

Lid driven cavity flow

Some of our recent works relate to dissipation discretization, aliasing and pattern formation in internal and external flows. The following two papers provide the results:

A new combined stable and dispersion relation preserving compact scheme for non-periodic problems, T.K. Sengupta, V. Lakshmanan and V.V.S.N. Vijay, J. Comput. Physics Vol. 228, pp. 3048- 3071, (2009).

Further improvement and analysis of CCD scheme: Dissipation discretization and de-aliasing properties. T.K. Sengupta, V.V.S.N. Vijay and Swagata Bhaumik, J. Comput. Physics doi:10.1016/j.jcp.2009.05.038 (2009).

The following animation shows the formation of a triangular vortex inside a lid-driven square cavity:

Observed modes by POD analysis of flow inside lid driven cavity are shown below .

NASA's Voyager discovered an storm encircling at the north pole of Saturn which is also observed as one of the POD mode( mode5 & 6 ) in a lid driven cavity flow.

The picture in the right shows Saturn, was taken by NASA's Cassini which showed a six-sided feature encircling the north pole of Saturn near 78 degrees north latitude by the visual and infrared mapping spectrometer.

It was discovered by Voyager's flyby in the early 1980's, Now Cassini's (2006) pictures prove that this is an unusually long-lived feature on Saturn.
