Magnetic Vapor Shield Mechanism for Protection of Material Surfaces Exposed to High Heat Load

Abstract

This project has been successful in predicting decreased erosion of surfaces exposed to high heat fluxes under railgun or electromagnetic launcher conditions. The significant reduction has come as a result of the proper modeling of the vapor shielding (VS) effect. Favorable comparison with experimental results supports our conclusion. A further decrease in surface erosion should come as a result of an applied magnetic field which should reduce turbulence in the VS boundary layer. Preliminary experimental measurements support this claim, but further theoretical work must be done which would include 2-D, and turbulent effects. Keywords: Plasmas physics; Mathematical models; Radiation transport; High heat flux; Surface erosion; Magnetic vapor shield; Melting/ablation.
