T1 - Model of chemical reaction kinetics for calculating detonation processes in gas and heterogeneous mixtures containing hydrogen peroxide JF - Combustion science and technology N2 - An approximate two-stage kinetic model of the chemical reaction in hydrogen-oxygen mixtures containing hydrogen peroxide, water, and inert diluents is developed. The model includes one differential equation for the calculation of the molar mass of the gas after the induction period and algebraic formulas for the calculation of the heat release, internal energy and thermodynamic parameters of the mixture. Based on this model, 2D numerical simulations of a multifront gas detonation wave are performed. These pioneering simulations correspond to the stoichiometric hydrogen-oxygen mixture with hydrogen peroxide and argon additions. An approximate model of chemical equilibrium in heterogeneous gas-condensed phase systems containing hydrogen peroxide is presented.

Under certain conditions, e.g. shock wave impact, phenomena can take place at this position that can have a significant influence on the explosion behavior of the system. In this work an investigation is presented about the existence of such phenomena on the surface of liquid cyclohexane with or without the existence of oxygen containing bubbles. The observations have been performed during the time before, as well as after, a detonation wave reflection on that surface. High-speed pressure and optical measurements have been applied. Apart from the experimental observations, also a theoretical analysis and discussion is presented in this contribution, which contains the comparison between calculated and experimental values.
