低马赫数 meaning in Chinese
low mach number
Examples
- Numerical fluxes considered in the explicit portion of the algorithm were evaluated by an implicit high - order compact scheme to augment stability . meanwhile , an implicit high - order compact numerical filter was used
显式一边的空间导数采用具有较高精度和良好数值稳定性的隐式高阶紧致差分格式，同时采用适于低马赫数流动计算的隐式高阶数值过滤方法。 - In order to accelerate the convergence speed , we employ the local time step , and implicit residual smoothing methods . finally , we use this method to get the steady solution of the flow around naca0012 and naca4412 airfoil at very low speed and some basic unsteady solution
本文对在低马赫数下绕naca0012翼型和naca4412翼型的定常流场进行了求解，结果和实验基本吻合，并对非定常运动情况进行了初步模拟研究，得出了一些有意义的结果。 - ( 5 ) we parallelize a real large cfd application lm3d and another application of explosion in a box by employing many useful techniques , for example , the divide - conquer method and the new mapping scheme mentioned above . these two parallel programs both achieve satisfactory performance
( 5 )针对三维低马赫数流动和爆炸冲击波模拟两个科学计算问题,将串行算法的改进与优化、区域与迭代空间分解、数据映射等技术相结合,实现了它们的高效并行程序,使性能得到显著提高。 - In order to improve the efficiency of the mesh generation , we employ the transfinite interpolation method . in low speed flow ( m < 0 . 05 ) , the low mach will aggravate the difference between eigenvalues of the system and make the convergence sharply difficult . as for this , we use the preconditioning method to remove it
另外，我们求解的是极低马赫数下的流场( m 0 . 05 ) ，极低的马赫数会导致可压流动方程十分僵硬而难以收敛，对此，我们对n - s方程进行了矩阵预处理。
