This simulation models 10 seconds of solid propellant combustion in a rocket motor using the Combustible Objects Model in FLOW-3D. The solid propellant grain is shown in orange and the steel casing in gray. Streamlines colored by gas velocity reveal the flow patterns in the chamber as combustion gas accelerates toward the nozzle. The propellant volume plot tracks the steady reduction in propellant mass over the 10-second burn, showing a linear regression characteristic of a well-designed grain geometry.
