When designing spacecraft with electric propulsion (EP) devices, it is important to assess spacecraft integration to ensure that the important components are not subject to significant sputtering by high-energy ions. In addition to the EP device and

To varying degrees, all experimental measurements are corrupted by real-world noise sources including electronic noise in the acquisition system, far-field perturbations in the surrounding environment, and local physical phenomena. This paper present

The radiosity view factor model commonly used in radiation heat transfer and computer graphics is applied to a free-molecular flow problem. This paper extends the model to sources with general distribution and includes the diffuse reflections from su

Relaxing the direct simulation Monte Carlo (DSMC) method to be compatible with variable particle weights has significant advantages when applied to simulations with a large density variation, as the statistical noise in the low density region can be

Standard area weighting methods for particle-in-cell simulations result in systematic errors on particle densities for a non-uniform mesh in cylindrical coordinates. These errors can be significantly reduced by using weighted cell volumes for density

A particle-in-cell Monte Carlo collision model is developed to explore dominant collisional effects on high-velocity xenon ions incident to a quiescent xenon gas at low neutral pressures. The range of neutral pressure and collisionality examined are
