Ideal detonation characteristics of biogas- hydrogen and -hydrogen peroxide mixtures

摘要

This article reports the ideal detonation characteristics of various mixtures of biogas-hydrogen and biogas-hydrogen peroxide with air. The results obtained by the chemical equilibrium calculations reveal the fundamental improvement of the biogas detonation characteristics when it is mixed with either H_2 or H_2O_2. However, a discussion is conducted to compare between the effects of each of those two secondary fuels on the detonation CJ velocity, pressure rise, and temperature of biogas detonation. It was found that in lean mixtures, H_2 provides higher detonation speed than H_2O_2 at the same equivalence ratio.
