N2 - A comprehensive numerical analysis is developed to study the combustion of liquid monopropellant in a small-volume vortex chamber. The instantaneous burning rate of the liquid propellant is obtained from well-caliberated experiments as a function of local pressure and temperature. The basis of the present work is a two-phase flow analysis based on the level-set approach. The model allows for a detailed investigation of the liquid-film motion and gas-phase flow development. As a specific example, the case with liquid nitromethane in a volume of 108 mm3 is examined systematically.
