“…Propellant based on hydrogen peroxide has a number of advantages such as high density, non-toxic, high specific impulse and others. In order to use the hydrogen peroxide as a propellant it must be of high quality and above 90% concentration to reduce the decomposition on the surfaces of contact [6][7][8]. High-concentrated hydrogen peroxide is very insensitive to detonation by shock or impact.…”

“…In work [10,11], an analytical model of the non-equilibrium evaporation of liquid droplets by using the Navier-Stokes system of equations is discussed. Numerical simulations of liquid droplet combustion in turbulent flows of gaseous oxidant are described in [12][13][14]. The equilibrium and non-equilibrium boundary conditions on the surface of a burning droplet are considered in [15][16][17].…”

AbstractMetal particles are widely used in space engineering to increase specific impulse and to supress acoustic instability of intra-champber processes. A numerical analysis of the internal injection-driven turbulent gas-particle flows is performed to improve the current understanding and modeling capabilities of the complex flow characteristics in the combustion chambers of solid rocket motors (SRMs) in presence of forced pressure oscillations. The two-phase flow is simulated with a combined Eulerian-Lagrangian approach. The Reynolds-averaged Navier-Stokes equations and transport equations of -model are solved numerically for the gas. The particulate phase is simulated through a Lagrangian deterministic and stochastic tracking models to provide particle trajectories and particle concentration. The results obtained highlight the crucial significance of the particle dispersion in turbulent flowfield and high potential of statistical methods. Strong coupling between acoustic oscillations, vortical motion, turbulent fluctuations and particle dynamics is observed.
