Zero-Dimensional Model

• Approximation Appropriate for:

  • Acoustic Time << Flow Time

• Constant Volume Combustion

  • Justified by High-Velocity Detonation

• Allows Closed Form Solution for:

  • Vacuum Back Pressure
  • Constant Specific Heats

• Numerical Solution of ODE’s for:

  • Arbitrary Back Pressures
  • Variable Specific Heats / Equilibrium Combustion
