Draw up and application of a computer program for roads ' plane curve coordinates 道路平曲线坐标计算程序的编制与应用
6 . a 3 - d flow and sediment model in curvilinear collocated grid is developed from 2 - d model ( 6 )非交错曲线网格三维水流泥沙数值模型,采用拟合曲线坐标和垂向坐标变换。
By procceding from the all - gaseous state navier - stokes equation and using eno difference scheme , the limited cold - flow jets produced by ignitors are numerically simulated in srm chamber . then the flow field structure and characteristics are analyzed 从曲线坐标下的完全气体n - s方程出发,采用eno差分格式,对点火发动机工作初期,在固体火箭发动机内腔形成的受限冷喷流流场进行数值模拟;在此基础上,分析了喷流的流场结构及特性。
