Our research experimentally, mathematically, and computationally investigated the singularity that forms at the tip of water droplets freezing on a flat surface (Snoeijer and Brunet, AJP 2012). We designed an apparatus to...
The position of the anode inside a Hall thruster is a very critical yet unexplored parameter in thruster physics. We present an innovative thruster that has a movable anode to test thruster efficiency and performance at...
Plasma thrusters have found increasing application for station-keeping of earth orbiting satellites as well as some interplanetary missions, yet a few of the finer details of the basic plasma physics of these thrusters remain...
in our case several blackened, corrugated aluminum mesh grids. The grids transfer their thermal energy to the passing air. This paper theoretically and experimentally investigates the optimal number of grids to maximize...
Many oscillatory systems of great interest exhibit pulsing behavior. The analysis of such oscillators has historically utilized a constant-phase model such as the Kuramoto equation to describe their dynamics. These models...
This project investigated the dynamics of 2-d easy axis magnetic spin systems. In particular, I studied the formation of intrinsic localized modes (ILMs) which arise from nonlinear behavior that manifests primarily as energy...
