TDBP Wave

Detonation, TDBP Wave (Taylor- Doring-Burkhardt-Pfriem Wave). Accdg to discussion given by Cook in Chapter 5, under Theoretical Wave Profiles (Ref 4, pp 92ff), Taylor (Ref 3) studied theoretically the p(x) and W (x) distributions behind plane and spherical detonation waves for gaseous expls and TNT, using the hydrodynamic equation  

For gaseous expls in which products of deton obey the ideal-gas law, eq (5.6) may be. integrated to give  

Here a = covolume v = specific volume of deton products v2 = specific volume at C-J.plane /3=(v2 — a) /(v- — v2), where v =sp vol of original expl and T= temperature of detonation, K 

Equation (5-8) is applicable in the range v2 v vlt i.e., between the C-J plane and the stagnation plane W (x) =0. The approximation in eq (5.8) is based on the observation that in this range of densities, temp T decreases during isentropic expansion at about the same rate that increases and the product (T/3) is therefore approx constant. The integral v2 

Detonation (and Explosion) Temperature must not be confused with Temperature of Detonation (or Explosion) described in the next item
