Recent Advances in Combustion Instability Analysis for Solid Propellant Rocket Motors.

Abstract

Three-dimensional combustion stability integrals are derived with effects of viscosity and vorticity incorporated. For clarity of presentation, the particle distributions in gas dynamics are not considered at this time. It is suggested that the finite element method can be utilized to advantage for complicated geometries and boundary conditions. Some of the initial finite element calculations are demonstrated for an illustrative purpose, pending a full scale numerical applications in the future. (Author)
