摘要:
采用大涡模拟方法,结合WENO格式、自适应网格加密技术和沉浸边界法,数值计算了高超声速柱体绕流问题,对三维方管中典型的的圆柱和方柱高超声速(Ma=5)绕流进行了模拟,计算结果给出了相同条件下激波与边界层作用下的分离区旋涡结构以及柱体尾流形态的异同。讨论了柱体前缘钝度对绕流流场结构的影响。研究表明,计算结果与实验结果相符。
Abstract:
Based on the large eddy simulation,the hypersonic flow(Ma=5)past the 3D circular and rectangular cylinders is simulated numerically using the WENO scheme,the adaptive mesh refinement technique and the immersed boundary method.The numerical results show the different and similar flow structures of the two cylinders and the vortex structure of the separation region with the interaction of shock waves and boundary layers under the same incoming flow condition.The effect of the dullness of the cylinder front-edge on the flow fluid is discussed.The calculation results are in good agreement with the experimental data.
