摘要/Abstract

摘要：

为了揭示复杂的流动机理,国内外提出了一系列高阶精度格式,其中加权非线性紧致格式(WCNS)具有良好的激波捕捉能力,已广泛用于复杂流动数值模拟,然而在模拟小尺度流动时分辨率不足、耗散偏大.在WCNS的框架下,借鉴基于目标本质无振荡(TENO)格式的加权策略,将间断检测和模板加权的新方法引入WCNS构造中,发展了一种7阶精度的WCNS7-T格式,通过一维激波管问题和二维黎曼问题等开展算例测试,并与传统的WCNS7-Z格式计算结果进行对比来验证新格式的改善性能.数值实验表明,WCNS7-T格式更好地抑制了间断附近的数值振荡,在提高分辨率和激波捕捉能力的同时也进一步降低了耗散.

Abstract:

In order to reveal the complex flow mechanism, a series of high-order precision schemes have been proposed at home and abroad, of which, the weighted compact nonlinear scheme (WCNS) has a good shock capture ability and has been widely used in the numerical simulation of complex flows. However, it has insufficient resolution and large dissipation in the simulation of small-scale flows. In the framework of the WCNS, by using the weighting strategy of the targeted essentially non-oscillatory (TENO) scheme for reference, this paper introduces the new methods of discontinuity detection and template weighting into the construction of the WCNS scheme, and develops a WCNS7-T scheme with a 7-order accuracy. Example tests are conducted through one-dimensional shock tube problem and two-dimensional Riemann problem. By comparing with the traditional WCNS7-Z scheme, the improved performance of the new scheme is verified. The numerical experiments show that the WCNS7-T scheme can better suppress the numerical oscillation near the discontinuity, improve the resolution and shock capture ability, and further reduce the dissipation.

Key words: compressible flow, high precision scheme, shock discontinuity, nonlinear weighting
