In the thesis,Gun for Balance that it'counterweight is solid pill is reseached in theory. Classical model of interior ballistics and physical model and mathematical model of two-phase flow is established in the thesis. Through numerical simulation. Launch precess of gun for balance is researched in the thesis. Primary content as follows.(1) Classical model of interior ballistics is established in the thesis. Through numerical simulation. Pressure distributing in the chamber of gun for balance and the character in the precess of launch of gun for balance is analysed.(2) Model of two-phase flow on the precess of launch of gun for balance is established. Results is gained through numerical simulation and computation. Physical process of launch of gun for balance is researched detailedly.(3) Through numerical simulation and compution on model of two-phase flow, Analysis is done on pressure distributing in the chamber of gun for balance. Safety analysis on the precess of launch of gun for balance based on structure of charges designed is done in the thesis. |
