About Me

I am a second year Ph.D. student studying Computational Science and Engineering at Georgia Institute of Technology. My primary research is on the modeling of gas liquid interfaces under high amplitude accelerations, but I also make regular contributions to MFC, an exascale ready multiphase flow code that scales to 10's of thousands of GPUs. When I'm not busy with school or research I enjoy spending time outdoors camping, hiking, and climbing or indoors playing board games.


Some of my Work

Vorticity Resulting from Flow Around an Airfoil

This video shows the vorticity sheeding of inviscid air over a NACA 2415 airfoil. A 3000 x 1500 x 500 cartesian grid is used to discretize the computational domain. The flow was simulated for 93k time-steps with snapshots saved ever 500 time-steps. The simulation required 19 hours of wall time using 128 A100 GPUs on NSCA Delta. The video shows the development of the isosurface at which the vorticity magnitude is 1000.


Vorticy Shedding of a Shock Inpinged Droplet

This video shows the atomization of a 3D water droplet in air impinged by a Mach 1.46 shockwave. A 2000 x 1000 x 1000 cartesian grid is used to discretize the computationl domain. The flow was simulated for 200k time-steps with snapshots saved every 1k time-steps. The simulation required four hours of wall time using 960 V100 GPUs on OLCF Summit. The video shows the development of the isosurface at which the vorticity magnitude is 100k.


Breakup of a Vibrated Air-Air Interface

This video shows the breakup of an air-air interface subjected to an oscillatory accelerating of 30g at 300 Hz in the vertical directions. A 500 x 500 x 500 catesian grid is used to discretize the Computational domain. The flow was simulated for 250k time-steps with snapshots saved ever 1k time-steps. The simulation required six hours of wall time using 132 V100 GPUs on OLCF Summit.
