Abstract
Numerical simulation of flows of an inviscid chemically active hydrogen–air mixture with overcompressed detonation wave in the quasi-two-dimensional and two-dimensional formulations is carried out. Simulation is carried out by integrating Euler’s equations supplemented with the equations of physico-chemical kinetics of hydrogen combustion in air with 18 chemical reactions in a 9-component mixture. In the quasi-two-dimensional formulation, steady-state flows with overcompressed detonation wave are obtained for various values of the excess air coefficient. In the two-dimensional formulation, a solution with overcompressed detonation wave is obtained and the effect of mixture inhomogeneity on the flow with formation of a detonation wave and its cellular structure is studied.
期刊介绍：
Fluid Dynamics is an international peer reviewed journal that publishes theoretical, computational, and experimental research on aeromechanics, hydrodynamics, plasma dynamics, underground hydrodynamics, and biomechanics of continuous media. Special attention is given to new trends developing at the leading edge of science, such as theory and application of multi-phase flows, chemically reactive flows, liquid and gas flows in electromagnetic fields, new hydrodynamical methods of increasing oil output, new approaches to the description of turbulent flows, etc.
