| Abstract | 把一阶迎风有限体积格式的高算法重构格式——高的迎风有限体积格式(GUVS)与不可压缩流和可压缩流SIMPLE算法相结合,数值模拟了各种宽深比的亚跨声速腔内流动.利用六阶高迎风有限体积格式(GUVS)在结构和非结构同位网格上模拟不同宽深比亚跨声速腔体流动,获得较好的数值结果.例如亚声速方腔流动的数值结果与Ghia等用多重网格技术获得的Benchmark解吻合得非常好;对不同宽深比腔内流动,数值模拟了大尺度漩涡、腔角小尺度漩涡的形成、分岔、破碎和边界层分离等演化情况,表明六阶精度GUVS具有分辨率高、稳定性好的良好性能. |
| Other Abstract | Some subsonic-transonic flows in cavities with different ratio of length to depth are simulated numerically using Gao’s upwind finite-volume schemes(GUVS) coupling with compressible and incompressible SIMPLE algorithm in this paper.GUVS is product of reconstructing first-order upwind finite volume scheme by Gao’s algorithm.Some subsonic-transonic flows in cavities with different ratio of length to depth are simulated numerically using Gao’s sixth-order upwind FV scheme on structured and unstructured collocated grids.Some excellent numerical results are obtained.For example,the numerical results for subsonic flows in rectangle cavity(i.e.lid-driven cavity flows) quite well agree with the benchmark solutions given by Ghia etal using multigrid technique,and flow characteristics of subsonic-transonic flows in cavities with different ratio of length to depth are also presented.Excellent properties of GUVS are proved by analysis and numerical tests. 更多 |
