Multi-scale modeling of solid rocket motors: Time integration methods from computational aerodynamics applied to stable quasi-steady motor burning

摘要

Here we consider the problem of efficiently computing the stable burn-back of a solid rocket motor when the motor is in the quasi-steady burning regime of operation. When the motor is modeled as a cavity that is filled with a compressible fluid with normal mass and momentum and energy injection from the solid propellant surface, the problem posed is a standard one in steady computational aerodynamics.
