Abstract

Nitromethane has many applications, including in racing, as a gasoline fuel additive, and as a monopropellant. To improve models, the pyrolysis of nitromethane was investigated experimentally in shock tubes and in a micro flow reactor with a controlled temperature profile (MFR), under dilute conditions. Several spectroscopic diagnostics were used in the shock tubes to follow the concentration time histories of CO, H2O (both using IR laser absorption), and nitromethane (UV light absorption). A quadrupole mass spectrometer was used to measure nitromethane, NO2, CH4, C2H4, and C2H2 at various temperatures with the MFR. Predictions for the CO and H2O levels were generally inaccurate, and the CH4, C2H4, and C4H4 predictions were poor in most cases for the MFR data. Importantly, all models largely differed in their predictions. A numerical analysis was performed to identify ways to improve the next generation of nitromethane models.
