 My research interests involve study of the following problems both experimentally and computationally:

1. Fluid instabilities. Study of various fluid driven instabilities in homogeneous and stratified flows (Experimental and computational).

2. Buoyant jet and plume dynamics. To understand plume behavior in stratified environments. This has high relevance to ocean and atmospheric mixing (Experimental work).

3. Multiphase flows over bodies. Effect of dispersed particles on bluff bodies and streamlined bodies. To understand turbulence characteristics and particle impaction in such flows. (Experimental and computational).

4. Rotating thermal convection. The idea here is to mimic the circulation patterns in atmosphere and to study mid-lattitude planetary waves that affect the weather & climate pattern. (Experimental)

5. Bio-fluid dynamics. Mixing due to swimmers in ocean that has effect on SST (Experimental and computational)

Experimental measurements using simultaneous Particle Image Velocimetry (PIV)-Planar Laser Induced Fluorescence (PLIF), and other imaging techniques.

Numerical modeling using Ansys FLUENT.

Other areas of interests are shock driven instabilities, and tackling industry problems. I am open to collaborative research.


Ongoing Research Projects

1. High-resolution diagnostics development for study of fluid instabilities and mixing, funded by IRCC, IIT Bombay.

2. Experimental study of flow dynamics and turbulent entrainment of jets/plumes in stratified environment, funded by Department of Science and Technology Young Investigator Research Grant.

3. Experimental and numerical study of superheated jets, In collaboration with GE Global Research India.

4. High resolution simultaneous PIV-PLIF measurements of flow dynamics and turbulent mixing in buoyant stratified jets and plumes, funded by Ministry of Earth Sciences.

5. Turbulence modulation in dispersed particle laden flows funded by IRCC, IIT Bombay

6. Rotating thermal convection, funded by ME departmental special funds.
