Shock tube study of artificial ignition of N2O:O2:H2:Ar mixtures
Problem of ignition acceleration is of crucial importance from both scientific and technological standpoints. In order to investigate detailed kinetics of ignition and ways of its acceleration experiments the were carried out behind the reflected shock wave for the temperature and pressure ranges 850-2100 K and 0.1-1.0 atm respectively. We examined ignition of N2O:H2:Ar = 1:1:8 and O2:N2O:H2:Ar = 0.3:1:3:5 mixtures. The autoignition, ignition by low temperature nonequilibrium plasma of nanosecond high-voltage discharge and flash-photolysis aided ignition have been compared. Numerical scheme to describe the autoignition in the system has been proposed and tested.
