Short Abstract: Unstable detonation in heptane vapor-air mixtires is numerically modeled by using three step chemical mechanism with two reversible reactions. The ignition condition is the gas with high velocity and high temperature. Three kinds of solution are obtained. First, as the velocity of ignition gas is slow the detonation fails to develop. Second, the pressure histroy becomes double oscillation after several single oscillations. The last is much comple solution that pressure is very irregular.
