摘要
液体工质电热化学炮内弹道过程的本质是高速等离子体射流与推进剂工质的相互作用并推动弹丸运动的过程.基于对该过程物理机理的现有理解,本文提出了用于描述液体工质电热化学炮的两维多相流模型,主要包括:描述等离子体与液体工质气态产物运动的两维湍流模型和描述由等离子体射流卷吸引起的液体工质颗粒运动的颗粒轨道模型。
The nature of interior ballistics process in a liquid propellant gun is the interaction between plasma injection and liquid propellant. According to the comprehension for the mechanism of this process, a two dimensional multi phase model for a liquid propellant electrothermal chemical gun has been presented, which includes the two dimensional turbulent equations for plasma and gas flow, and the equations for droplet trace due to entrainment of plasma injection. The results of numerical calculation also have been provided.
