Numerical Simulations of Gaseous Detonations

Detonations with One-Step Chemistry

Initial Conditions

For instance for

%MATHMODE{ \gamma=1.2,\; Q_0=50,\; E_0=50 }%

two different exact solutions under the assumption of a stationary detonation wave are plotted in Fig. 2.1. Herein, f denotes the overdrive parameter, which is defined with respect to the corresponding Chapman-Jouguet velocity by

%MATHMODE{ f:=\left(\frac{d^\star}{d_{_{CJ}}}\right)^2=\left(\frac{D}{D_{_{CJ}}}\right)^2\;. }%

Figure 2.1: Stationary ZND solutions. The abscissae display the normalized distance behind detonation front. Top: f =1.0, bottom: f =1.8.
