An adaptive grid scheme controlling cell area is used to generated grids in the divergent section of symmetric annular nozzle, and the generated grids are used in the flowfield calculation through the uncoupled way. The elliptic equations are used to generate grids in three dimensional regions of FDN divergent section, the source terms used in the equations employ a mathematical form which is independent of the boundary shape and of the boundary grid point distribution, the free parameters contained in the source terms are determined by the two restraint conditions, the intersection angle of transverse grid lines with boundaries and the local curvature of the transverse grid lines at the boundaries, and the interior grid distribution controlled directly by the grid point distribution assigned on the boundaries is realized, it makes the grid more clustering near the nozzle wall. For the generated grids in the whole computational regions have a good smoothness and orthogonality, the accuracy of calculation in the flowfield is ensured.

对轴对称的环形喷管采用控制网格面积的自适应网格方法对扩散段部分进行了网格生成，并通过非耦合方式应用于喷管的流场计算中；对强制偏流喷管扩散段内的三维区域采用椭圆型方程进行网格生成，方程中的源项采用了与边界形状和边界网格点分布无关的数学形式，源项内的自由参数由横向网格线与边界的交角及横向网格线在边界处的局部曲率两个约束条件来确定，实现了由边界上的网格分布直接控制内部的网格点，使壁面附近具有较密集的网格，并且在整个计算区域内的网格都具有良好的光滑性和正交性，从而保证了流场计算的准确性。

Critical angle of refraction - semi-circular cylindrical mobile light source, the incident angle change the size of refraction angle to change at this time, when the refraction angle = 90 degrees, which is critical at this time angle of incidence angle, the critical angle of water at 40 degrees large about anything mobile source of water in the water screen that is a reflection of light, a phenomenon that total reflection.

光折射的临界角定义：光折射角=90度时，入射角即为临界角，按二方法，将半导体激光光源去掉铁夹，吸附在右下角的铁板上入射光对准中心，即产生折射光线，沿半圆形柱面移动光源，改变入射角的大小，这时折射角也改变，当折射角=90度时，这时入射角即为临界角，水的临界角大的在40度左右，再做移动光源在水中的水屏即出现反射光线，这种现象称全反射。
