F.X.Timmes, my vitae
Zeldovich, Von Neumann, and Doring (ZND, 1943) independently formed a set of differential equations for a detonation which overcame the deficiencies of the Chapman-Jouget detonation model:
The ZND solution gives the:
- width of the fuel-ash region
- spatial variation of the hydrodynamic and thermodynamic variables
- the self-sustating detonation solution
- global integrals which reduce to the Chapman-Jouget solution.
