Solving the reactive low-Mach Navier-Stokes equations with high-order adaptive methods in time is still a challenging problem, in particular due to the handling of the algebraic variables involved in the mass constraint. We focus on the one-dimension

International audience; In solid rocket motors, aluminum particles are included in the propellant to improve the global performances but the distributed combustion of these droplets is suspected to be a driving mechanism of hydrodynamic instabilities
