Continuum Kinetic Simulations of Plasma Sheaths and Instabilities
A careful study of plasma-material interactions is essential to understand and improve the operation of devices where plasma contacts a wall such as plasma thrusters, fusion devices, spacecraft-environment interactions, to name a few. This work aims to advance our understanding of fundamental …

Application of Ab-initio Quantum Chemistry Techniques to Hypersonic Flows for Plasma Blackout Alleviation
Plasma blackout in hypersonic flows produced by weakly-ionized air plasma sheaths is a phenomenon that attenuates or completely blocks communications with vehicles flying in a high-enthalpy flow environment. The ability to mitigate this issue can be useful from various re-entry vehicles to …

Space-Charge Saturation and Current Limits in Cylindrical Drift Tubes and Planar Sheaths
… the fundamental collective behavior found in plasmas, especially in plasma sheaths. A plasma sheath is the transition region between a bulk plasma and an adjacent plasma-facing surface. The sheath controls the loss of particles from the plasma in order to maintain neutrality. Using a fully …

Cubesat Wakes in the Earth’s Ionosphere
… to characteristic length scales of the space plasma environment, namely, the Debye length. Although spacecraft-plasma interactions- surface charging, plasma sheaths and wakes- have been well-studied for larger satellites, they are less understood for CubeSats.</p> <p>The Dynamic Ionosphere …

A Continuum Kinetic Investigation into the Role of Transport Physics in the Bohm Speed formulation
When plasmas come in contact with the boundaries that confine them, various complex processes occur between the plasma and the materials in the boundary. These processes, called plasma-material interactions (PMI) lead to physical and chemical modifications in the materials and in the plasma. In the …
