摘要

为研究全等式模块装药背景下单模块装药点传火过程中火药颗粒群的散布特性及药粒堆积形态

提出三维非稳态气-固两相流模型

在取不同的模块药盒装填位置的初始条件下进行数值模拟

其中柱状火药颗粒由球元法构建。通过离散单元法(DEM)获得的数值结果与试验结果进行比较

发现上述模型是合理可行的

并且比球形颗粒模型更为精确。研究结果表明:在模块药盒初始装填位置距底火端分别为10mm、40mm、70mm和100mm时

终态药粒分布于模块药盒右端面外侧

依次呈水平堆积和坡状堆积;随着模块药盒与底火端的距离增加

水平堆积轴向长度从293.3mm减少至203.8mm

坡状堆积的坡角由22.01°降为19.82°

即随着模块药盒向右移动

药粒水平堆积起点右移

轴向长度呈线性缩短

但坡状堆积轴向长度大致不变

坡度变缓。

Abstract

A three-dimensional unsteady gas-solid two-phase flow model is proposed to investigate the distribution and stacking characteristics of propellant pellets during the ignition and flame-spreading processes of a single modular charge in the uni-modular charge. Numerical simulations are carried out under different initial conditions at the filling positions of modular cartridges

in which cylindrical pellets are constructed by the multi-element method. The numerical results obtained by the discrete element method (DEM) indicate good agreement with the experimental results

and that the cylindrical particle model is more accurate than the spherical particle model. The simulation results suggest that: when the modular cartridge’s initial loading location is 10mm

40mm

70mm

and 100mm from the primer

the pellets are finally distributed on the outside of the right end of the cartridge

showing horizontal and sloped stacking in turn; the axial length of horizontal stacking is reduced from 293.3mm to 203.8mm

and the angle of the sloped stacking decreases from 22.01° to 19.82° when the distance between the initial loading position of the modular cartridge and the primer increases from 10mm to 100mm; in other words

as the modular cartridge moves to the right

the starting point of horizontal stacking moves to the right

and the axial length decreases linearly; however

the axial length of sloped stacking is almost unchanged

and the slope becomes flat.
