Modeling of normal and erosive burning rate of a hot double-base homogeneous propellant

Abstract

The burning rate of a hot double-base homogeneous solid propellant is modeled by the numerical solution of the conservation equations characterizing the primary flame using a global kinetic scheme. The increase of the burning rate above the solid surface is modeled by an enhancement of the heat transfer between the flame and the wall by the turbulent mechanisms. The calculated burning rate overshoot, generally called erosive burning, accurately predicts the experimentally observed phenomena.
