Development of Hall Thruster Erosion Model
Team Lead: Prof. Julian J. Rimoli
2011-2012: Working towards the construction of a multi-scale and multi-physics model of plasma-induced wall erosion, the modeling effort has been focused on the implementation of an algorithm for the geometric representation at the mesoscale level of the polycrystalline compound as well as a bi-material model for the thermal transfer component of the model. Additionally, GTMM has worked with GTRI to characterize the roughness of BN samples using contact profilometry and employed Scanning Electron Microscopy (SEM) and Energy-Dispersive X-Ray Spectrometry (EDX), finding measurable implanted Xenon in samples from a stored HET channel.
