为了提高大雷诺数流动的有效分辨率，提出了一类空间高度对称的不可压缩粘性流体三维周期流动，并将其用于大雷诺数流动的数值模拟。在1/64体积的周期性盒的区域中的速度的单个分量的信息足以描述整个速度场。因此，所需的存储器可以减少到一般非对称周期流所需存储器的1/192。
A class of three-dimensional periodic flows of an incompressible viscous fluid with high symmetry in space is proposed to be used for numerical simulation of large Reynolds number flows in order to increase the effective resolution. Information for asinglecomponent of the velocity in a domain of 1/64 in volume of a periodicity box is sufficient to describe the whole velocity field. Necessary memory therefore may be reduced to 1/192 of that required for a general non-symmetric periodic flow.
