Effect of Ion Thruster Plume-Thermosphere Interaction on Satellite Aerodynamics in Very Low Earth Orbit

Satellite operations in Very Low Earth Orbit (VLEO), altitudes below 250km, are highly appealing for flexible, high-performing and economical spacecraft operations to deliver low-cost communications and Earth observation data. However, the mission lifetime in VLEO is significantly limited due to the aerodynamic drag from the momentum exchange between the residual atmosphere and satellite. This article describes a recent research of S. Andrews that utilized our Starfish plasma simulation code. (May 25 2020)

Starfish DSMC Tutorial: Supersonic Jet and Argon Diffusion

This tutorial shows you how setup a DSMC simulation using Starfish. We model expansion of an atmospheric pressure gas to a low pressure reservoir and also compute self-diffusion coefficient of argon. (Apr 14 2017)

Starfish Tutorial Part 5: Collisions and Chemical Reactions
