THE FLOW FIELD BEHIND A SPHERICAL DETONATION IN TNT USING THE LANDAU- STANYUKOVICH EQUATION OF STATE FOR DETONATION PRODUCTS

Abstract

Calculations were made of the flow field in the isentropic region behind a detonation wave in TNT, using the Landau Stanyukovich equation of state for the detonation products (as described by Zeldovich and Kompaneets). adjustable constants in this equation were evaluated by imposing ideal gas behavior on the detonation products in the large expansion (low density) limit, and by fitting to an experimental curve of detonation velocity versus loading density. Calculated values of Chapman-Jouguet variables correspond fairly well with experimental values at various loading densities, with the exception of the temperatures, which seem to be far too low. This is connected with the fact that the theory predicts an upper limit to the loading density at which an explosive will detonate; at this point the thermal energy vanishes and only the elastic energy contributes to the energy of detonation.
