Abstract
In order to explore the mechanism and the model of slag generation in solid propellant rocket motor, the two phase flowfield has been simulated using a combined Eulerian-Lagrangian analysis. The motion of the particulate phase was tracked with a stochastic model. The droplet size distribution in the chamber and the two captive rules were considered. Finally, the influence of different coefficients of restitution on slag calculation was investigated. The calculated result shows that the lowest slag weight is 0.201% and the highest slag weight is 0.287% of the total weight of Al2O3. The results are accurate and credible compared to the experimental data.
