Computational simulations are the main method to study fluid instability during an implosion in inertial confinement fusion 数值模拟是惯性约束聚变内爆中流体不稳定性研究的主要方法。
We also used 5 levels amr grid to simulate the helmholtz multi - fluid instability , but not compared the cpu time with each other yet 我们也采用过五级剖分,由于均匀细网格的计算量太大无法比较耗费的时间。
Fluid instabilities become more complex in convergent geometry than planar geometry and many essential problems keep undone 相对平面几何而言,收缩几何中流体不稳定性问题更加复杂,目前研究得不够多,许多基本问题有待深入研究。
In this article , some results of the theoretical derivation and computational campaign performed to study the fluid instabilities in convergent geometry are presented 本论文通过理论分析和数值模拟方法,对收缩几何中的一些流体不稳定性问题进行了研究。
In inertial confinement fusion , a variety of fluid instabilities can destroy the symmetry and integrity of the capsule , and even fail the ignition . the understanding of the growth of perturbations is of extreme important for achieving the ignition and high gain 在惯性约束聚变内爆过程中存在各种流体不稳定性,它们能够破坏靶丸的对称性和完整性,使得点火失败,因此深入地理解收缩内爆过程中流体不稳定性的发展规律,对于实现点火与高增益聚变是至关重要的。
Numerical results are consistent with that of sandia laboratory experiment and agree with that of cth code too . an adaptive mesh refinement under 2d euler structure grid for multi - fluid flow is developed for resolving richtmyer - meshkov , rayleigh - taylor and helmholtz multi - fluid instabilities , and the high resolution interface properties can be obtained 数值模拟多介质流体richtmyer - meshkov , rayleigh - taylor , helmholtz界面不稳定性,用levelset函数定义euler坐标系中界面附近网格自适应判据,使得网格剖分更加合理,既能提高计算精度又能节省计算时间。
