Abstract
Abstract : Procedures for relating waste heat to entropy increases in a shock wave are described. Numerical coefficients for Mie-Gruneisen equations of state are obtained for several liquids. These equations of state are used to calculate the flow produced by a 1.6-cm-radius sphere of C-3-like explosive in a surrounding liquid. Specific entropy increase as a function of radius is included in the calculation, and this is used to determine the waste heat for a 3.85-cm-radius liquid burster. (Liquid-to-explosive mass ratio is about 10.) Calculations for glycerine, for two different water equations of state, and for ether yield total waste heats equal to (.32 + or - .03) x (explosive energy). Close agreement between calculations for two different water equations of state produces considerable confidence in the reliability of this result. On the basis of these calculations, evaporation of several liquids is estimated. If decomposition can occur or if more precise values of waste heat are needed, more exact equations of state will be required; the present calculations can be readily modified to accommodate such equations.
