摘要:
为了探讨弹丸底部流动规律,该文采用WangJ.C.T的二阶TVD有限体积格式求解Navier-Stokes方程进行枪弹绕流模拟。文中模拟了来流马赫数3和5的枪弹绕流,得到满意的波系结构,计算结果表明底部阻力系数随马赫数的关系与实验结果符合良好,该方法除计算精度高、激波分辩率高和数值稳定等优点外,对边界处理比较灵活,对网格的生成质量和初场布置要求不高
Abstract:
T o invest igate f low at cart ridg e base, this paper present s numerical simulatio n of flow around car tridge w ith a 2nd-order accuracy T VD f inite volume scheme applied to solve Navier -Stokes equations, w hich is based o n Wang J. C. T scheme. Flow aro und cartr idge w ith f ree f low Ma = 3 and 5 ar e calculated, ag reeable w aves st ruct rue is o btained. The result s ver ify that the relat io n betw een drag coeff icient of base and Mach number is in a g ood agree ment w ith the ex periment . Besides high accuracy , high resolution of shock w ave, nonoscillation, the method is easier to deal w ith the boundary condition and less st rict w ith cell specif icat ion and f irst flow field parameter s ar rang ement .
