Novel Numerical Methods for Electric Propulsion Modeling

The electrostatic particle in cell (ES-PIC) method has become an invaluable tool for studying the physics of electric propulsion devices or their interaction with spacecraft components. However, the classic approach utilizing a Cartesian grid, fixed macroparticle weight, and an imposed separation between a "device" and a "plume" domain has led to a number of difficulties including the inability to resolve fine geometrical features, noise in the representation of low density species, strong assumption on boundary conditions, and an artificial break in the governing physical equations. Submissions are thus sought from the community on novel numerical techniques for modeling electric propulsion devices, their components, and spacecraft interactions. Topics of interest include, but are not limited to: - Direct kinetic "Vlasov" or hybrid-Vlasov approaches - Meshfree techniques - Models for resolving the dynamic surface / plasma interface - Collisional algorithms beyond classic DSMC, plasma / surface chemistry models - Hardware-specific approaches, including embedded and edge-computing numerical techniques - Multiphysics models capturing effects such as charging, erosion, heat transfer, and radiative emission - Multifidelity and reduced-order models, physics-based machine learning - Other novel numerical techniques
