Research interests

You may want to have a look at my Ph.D. thesis, submitted in the mathematics department of MIT in July 2003. It is a big file though, due to the number of pictures.

Sedimentation in a stratifed ambient

My first paper was written in collaboration with John Bush and Bev Thurber and is concerned with particle clouds. My contribution was to model the flow of a particle cloud and simulate numerically its progression. This paper was published in the Journal of Fluid Mechanics in August 2003, vol 489, pp 29-54.

Particle clouds in homogeneous and stratified environments

My second paper was written in collaboration with Tom Peacock and John Bush and is concerned with the Boycott effect in a stratified ambient. It was published in the Journal of Fluid Mechanics in April 2005, vol 529, pp 33-49.\par

The Stratified Boycott Effect

My third paper was written in collaboration with Tom Peacock and John Bush is concerned with the Boycott effect in Magma Chambers. It was be published in the Geophysical Research Letters in March 2004, Vol. 31, No. 5, L05611

The Boycott Effect in Magma Chambers

My research is also concerned with the fundamentals of settling particles in a stratified ambient, the time evolution of the concentration of particles and the instabilities that may result from settling in a stratified ambient. This paper has been published in Physics of Fluids in July 2005.

Hindered settling in a stratified ambient

In January 2004, I have submitted to the Computer & Fluids journal an article written in collaboration with Vincent Piche, Eckart Meiburg and using an idea from Moshe Strauss on numerical simulations of gravity currents. This paper is currently in press

Evaluation of a simplified approach for simulating gravity currents over slopes of varying angles

In August 2004, I have submitted to the Journal of Geophysical Research an article written in collaboration with Moshe Strauss, Eckart Meiburg, Ben Kneller and Mike Glinsky on numerical simulations of resuspensing gravity currents. This paper is currently in press

High resolution simulations of resuspending gravity currents: conditions for self-sustainment

And videos of such simulations may be found here

Angle too small for self-sustainment

Angle sufficient for self-sustainment

I am currently working on simulations of interfactial flows, in particular studying how drops slowly coming in contact with a reservoir of the same fluid sometimes coalesce ONLY PARTIALLY, leaving behind a daughter drop of approximately half the diameter of the mother drop. The daughter drop then undergoes a similar process, which leads to a cascade of events (this phenomenon is also known as multiple coalescence). You can see a few
