Here is my appointment calendar.

Research Areas: CFD modelling, multiphase transport processes

My research interests center around computational aspects of fluid mechanics and transport phenomena. The series of structured transitions exhibited in a class of hydrodynamic stability problems are being investigated using recent algorithms from bifurcation theory and are also being verified in experiments using Laser Doppler anemometer.

In collaboration with Prof. Minev, we are developing next generation algorithms for direct simulation of multiphase flows with many particles using fictitious domain methods and deformable bubbles and droplets.

In another area, we are learning about issues related to modeling multiphase flows in industrially important flows. These include modeling the tray hydraulics of a distillation column, flow in packed towers, design of structured packings, erosion/corrosion in pipelines, SOFC fuel cells, sedimentation, bubble column dynamics, polymeric flows in twin-screw extruders  etc.

A Panel discussion on ethics in Science & Engineering

If you have a powerpoint viewer, you can view the slides that can help in providing some food for thought on such issues.
