基于 HWCNS 格式的紧致插值方法研究
Investigation of compact interpolation based on HWCNS schemes
摘要
Abstract
Finite difference methods are always advancing to obtain higher spectral resolution with robust discontinuities-capturing capabilities.Following HWCNS formation,a new high-order nonlinear compact interpolation is proposed,then the seventh-order compact HWCNS scheme is developed and its spectrum feature is presented.Several typical cases are carried to verify the performance of the new method in this paper.In terms of computational efficiency and accuracy of the numerical results,the present compact in-terpolation is superior to the explicit fifth-order HWCNS and seventh-order WENO schemes for simula-tion of flows characterized by multiple scales and long-term evolution include discontinuities,which is in accordance with the result of spectrum analysis.关键词
