Prediction of Basic Operation of Electro-Spray Thrusters Using High Fidelity Modeling
Abstract
The objective of this proposal is to develop a high fidelity, physically accurate, three dimensional, unsteady model of the porous flow, ion mode electro-spray systems to computationally analyze the various failure modes of electrospray thrusters to optimize operational lifetime. The major life-limiting physics is grid impingement within the extractor and accelerator grids in the Interaction Region. This failure mode is the result of off-axis propellant emission due to overspray and Coulombic expansion of the beam, therefore requiring a comprehensive analysis of the droplet dynamics throughout the system.
