Quantification of detonation regularity

Physical parameters as indicators for detonation regularity have been previously identified; however, a metric for the degree of regularity has yet to be defined. Quantifying the degree of regularity in cellular detonations offers valuable insight into their stability and potential failure. An experimentally derived regularity parameter, the coefficient of variation of velocity (( σ / μ ) V/DCJ ), is defined. This regularity parameter forms the finite boundaries relative to the effective activation energy using statistically significant and temporally resolved experiments.
