提出了一种新的截断误差减小方法。该方法是利用在粗网格 ( 2 h)上估算截断误差进而减小在原始网格( h)上的误差的迭代过程 ,最终目的是利用粗网格得出更精确的结果以及发展一种新的粗网格直接数值模拟方法
A new truncation error reduction method is proposed. This method utilizes an iterative process of estimating the truncation error on the coarse grid (2 h) and thus reducing the error on the original grid (h), with the ultimate goal of using coarse grids to derive more accurate results and to develop a A new method of direct numerical simulation of coarse grids
