V.VoroninLavrentyev Institute of Hydrodynamics of SB RAS, Lavrentyev str, 15, 630090 Novosibirsk, RUSSIAA numerical simulation of continuous gas detonation in the combustion chamber based on the Navier-Stokes equations, taking into account turbulence and diffusion of substances, is carried out. A comparative analysis of the efficiency of detonation combustion of fuel depending on the geometric parameters of the chambers is performed. Three possible camera types are considered. Fuel and oxidizer were fed separately into the chambers through nozzles at a certain angle to the chamber surface. The detonation process was largely determined by the intensity of the turbulent mixing of reagents (hydrogen and oxygen). Calculations show that the type of camera with a flat radial geometry is the most optimal to establish a stable detonation regime.1112023111202310911311https://wseas.com/journals/fluids/2023/a225113-009(2023).pdf10.37394/232013.2023.18.11https://wseas.com/journals/fluids/2023/a225113-009(2023).pdfVojciechowski B.
