通过分析格式的耗散关系和重线性化技术,发展相应格式构造技术,提出了一类中心型的三阶非线性格式,格式具有与NND格式相当的网格模板。由于格式的线性形式具有很好的耗散特性,同时重线性化技术的使用使格式在光滑区尽量采用线性形式,从而理论上提升了计算对旋涡等结构的分辨和保持能力;另一方面,格式的非线性机制使格式在非光滑区退化为类NND格式,实现耗散和稳定机制。验证计算表明,格式能够开展粘性和旋涡及脉动流场的计算应用,算法形式简单,便于工程应用,容易进行有限体积推广。 By analyzing the dissipation relation and re-linearization of the format, the corresponding format construction techniques are developed. A central type of third-order nonlinear format is proposed, which has a grid template equivalent to the NND format. Due to the good dissipation characteristic of the linear form of the format, the use of the re-linearization technique makes the format as smooth as possible in the smooth area, which theoretically improves the resolution and retention of the vortex structures. On the other hand, The non-linear format of the format degenerates the format into a class-like NND format in the non-smooth region, achieving dissipation and stabilization mechanisms. Verification calculation shows that the format can carry out the calculation of viscosity and vortex flow and pulsation flow field. The algorithm has the advantages of simple form, easy application in engineering and easy extension of limited volume.
