“…The EGGR coefficient can predict the plasma propellant interaction process very well. However, the EGGR coefficient is semi-empirical, suitable only for the given propellants [28]. Therefore, a more comprehensive model of the PPI is still required.…”

Plasma ignition technology has been widely used for decades due to its great improvement in enhanced burning rate. However, the interaction process between the plasma jet and the solid propellant is still far from being elucidated. In this paper, coupling the flow model of plasma jet and the chemical reaction model of propellants, a more comprehensive model for predicting the plasma enhanced burning rate is presented. Three types of energetic thermoplastic elastomers propellant are involved. In addition, the closed bomb vessel test is conducted to investigate the burning characteristics of propellant under the action of plasma for comparison. It demonstrates that the enhanced combustion phenomenon of propellants in the experiment can be well described by an enhanced burning rate coefficient epsilon calculated with the model, which could reflect the effect of plasma jet to some extent. The results show that the composition of the energetic material and its surface temperature are the key factors influencing the plasma-enhanced combustion. This model would bring some insight on the interaction mechanisms between plasma and different propellants.

“…Electrothermal chemical launch technology, which is an advanced high-velocity propulsion technology, is widely interested by scholars [1]. Electrothermal chemical guns can be classified into solid propellant electro-thermal chemical guns [5] [6] and liquid propellant electrothermal chemical guns (LPETCG). Compared with solid propellant, liquid propellant has a higher packing density and chemical energy and is easy to realize loading automation.…”

The interaction mechanism between the plasma and liquid is a key problem for the electrothermal chemical launch technology. To investigate this problem, a simulated experiment for the expansion process of a plasma jet in the working fluid is carried on. Based on this experiment, a two-dimensional axisymmetric unsteady theoretical model is established to reveal the plasma-liquid interaction flow field pattern. The results show that a typical Taylor cavity forms as the plasma jet expands in liquid. The induction effect of the stepped-wall structure enhances the radial expansion of the plasma jet. An arc-shaped pressure wave is generated at the front of the plasma jet and then evolves into the plane wave. A high-pressure area forms at the head of the plasma jet and then moves downstream. There is a strong plasma-liquid turbulent mixing at the interface, especially near the steps and the nozzle exit area.
