Effect of non-equilibrium plasma on decreasing the detonation cell size

Résumé

The effect of a volumetric nanosecond discharge on detonation cell size was demonstrated experimentally in a detonation tube test rig. The experiments were performed in CH 4 :O 2 :Ar=1:2:2 mixture, at initial pressure 180 mbar and ambient temperature. The plasma was generated by two consecutive pulses of −50 and −32 kV amplitude on the high-voltage electrode and 25 ns pulse duration. The analysis of the detonation cell size with and without plasma generation was performed via sootedplate technique. The detonation cell size was reduced by a factor of 1.5 − 2, while passing through the region of the discharge.
