摘要
建立了火药颗粒运动的两维颗粒轨道模型，用欧拉法描述气相场，用拉格朗日法描述固相颗粒，并采用单元内颗粒源方法，对某中心点火结构３０ｍｍ火炮的点传火过程进行了数值模拟．
An axisymmetrical particle trajectory model of a gun with centercore igniter is estaslished. The gas field is described by Eulerian system, whereas the propellant particles are described by the Lagrangian approach, in which all the propellant particles at different initial postion are trailed. The numerical calculation ignition and flames preading processes in a 30 mm gun are carried out. The numerical results are good.
