Transient surface heating in hot, burning flows
Abstract
Work currently being performed to investigate the fundamental mechanisms of wear and erosion in gun barrels and other systems involving hot propellant flows is described. In particular, analysis is presented of timewise changes in the surface-temperature distribution in response to transient heat fluxes at the wall. Results show sizable increases in the wall temperatures so that melting and erosion of the solid material may result due to hot turbulent flows over the surface.
