本文提出了两种新的用于可压缩湍流直接数值模拟的对称韦诺方法。该方案的目的是最大限度地提高精度和带宽的顺序，同时最大限度地减少耗散。介绍了计算公式和相应的系数。正则流问题的数值解用于确定数值格式的耗散和带宽特性。此外，在衰减的各向同性湍流和超音速湍流边界层的湍流流动的直接数值模拟的带宽优化方案的适用性和准确性进行了评估。
Two new formulations of a symmetric WENO method for the direct numerical simulation of compressible turbulence are presented. The schemes are designed to maximize order of accuracy and bandwidth, while minimizing dissipation. The formulations and the corresponding coefficients are introduced. Numerical solutions to canonical flow problems are used to determine the dissipation and bandwidth properties of the numerical schemes. In addition, the suitability and accuracy of the bandwidth-optimized schemes for direct numerical simulations of turbulent flows is assessed in decaying isotropic turbulence and supersonic turbulent boundary layers.
