Interaction of Moving Shock with Thin Stationary Thermal Layer,

Abstract

An analytical model is presented for the interaction between a moving shock and a thin thermal layer of semi-infinite extent. The fluid is assumed to be inviscid and ideal. The model is based on flow field characteristics deduced from the detailed numerical code calculations of Schneyer and Wilkins (1984). Flow field properties of interest include the peak surface (stagnation) pressure at the base of the incident shock, the forward extent of the shock-induced precursor, and the surface pressure at the latter location. Good agreement with Schneyer and Wilkins is obtained subject to appropriate choice of an arbitrary constant k introduced into the analytical model. Further validation of the model is needed. Keywords: Nuclear Blast; Shock Wave; Thermal Layer; Thermal Precursor.
