Description
Summary:A three-dimensional numerical simulation of the combustion chamber of a promising engine with a rotating detonation wave is performed. The calculations are based on the Navier – Stokes system of equations for multi-species gas with turbulence modeling and chemical interactions. Acetylene is used as a fuel. To describe the combustion of acetylene, a simplified chemical kinetic mechanism is used involving the following components: C2H2, CO, CO2, H2, O2, H2O, OH, O, H, N2. An isochoric autoignition test for the stoichiometric mixture was processed using this kinetics. During a computational experiment, the combustion chamber was 5 cm in diameter, and 5 cm in length; it was fed by a stoichiometric mixture from the injection system at the base of the chamber. A single-wave mode of a stable detonation wave was obtained in the case studied.
