Modeling the combustion of a hydrogen-air mixture in a rotating detonation wave

The aim of this work is a numerical study of flows in annular channels with combustion of a hydrogen-air mixture in detonation waves. The flow simulation with one detonation wave is carried out on grids with various cell sizes. Based on the results obtained, the convergence of solutions is calculated. To study the grid convergence the flow parameters averaged over time and space are monitored. Based on the data obtained on the convergence of the solution, a flow with two detonation waves in the channel is simulated. The features of the obtained solutions that arise on grids with sufficiently high resolution are considered.
