Numerical Simulation Study on the Law of Plasma Generated by Propellant Combustion

To research the rules of plasma generated by propellant combustion, the physical and chemical process of the propellant combustion was analyzed. Mathematical model of plasma density was established, then the numerical simulation analysis of the gunpowder combustion generating plasma rules were carried out. The numerical simulation results were compared with the experimental results, and the correctness and feasibility of the model were determined. Finally, using the established mathematical model, the effect of different structural parameters of charge on the plasma was analyzed, and the plasma density change rule was obtained. The study laid the foundation for the next step to improve plasma concentration.
