Detonation Combustion Control Using Preliminary Preparation of the Gas Mixture

The aim of the present study is to calculate the process of detonation combustion of gas mixtures in engines. Development and verification of 3D transient mathematical model of chemically reacting gas mixture flows incorporating hydrogen was performed. Development of a computational model based on the mathematical one for parallel computing on supercomputers incorporating CPU and GPU units was carried out. Investigation of the influence of computational grid size on simulation precision and computational speed was performed. Investigation of calculation runtime acceleration was carried out subject to variable number of parallel threads on different architectures and implying different strategies of parallel computation.

Partial Dissociation

Using a detailed kinetic model of chemical interaction, numerical investigation of influence of a preliminary preparation of a stoichiometrical hydrogen-air mixture (decomposition of some volumes of molecular hydrogen and molecular oxygen gases into atomic gases) on characteristics of a propagating detonation wave has been carried out. It has been obtained that the preliminary partial dissociation of the gas mixture results in an essential decrease of the detonation cell size and a small increase of the self-sustained detonation wave propagation velocity. Due to the established detonation combustion features, preliminary preparation of the mixture can be used to prevent destruction of a detonation wave in channels with both a single transverse barrier and a barrier domain.
