Research on plasma formation of ionized seeds under the influence of gunpowder gas

In order to study the plasma generation of ionized seeds under the action of gunpowder gas, a mathematical model under the condition of closed bomb (constant volume) was established, and a plasma test system was designed. Experiments were carried out with a certain type of artillery propellant and different kinds of ionized seeds. The results show that the ionized seeds can generate plasma under the action of gunpowder gas, and the electron densities are 2.25×10¹⁸m⁻³ and 4.63×10¹⁸m⁻³ after adding potassium salt and barium salt, respectively. The strontium salt ionization effect is better than the potassium salt. Under the test conditions, the simulation results are roughly in agreement with the test data.
