在GPU上实现了虚拟通量法（VFM）与人工压缩性法（ACM）相结合的方法来模拟不可压圆柱非定常流场，在GPU上实现了格子Boltzmann方法（LBM）来模拟不可压湍流。本文采用LBM和VFM相结合的方法计算了圆柱绕流的非定常流场。计算了圆柱后双涡长度和Strouhal数随时间的变化，并与其他研究者的计算结果进行了比较，同时给出了GPU的加速比。
The authors implemented artificial compressibility method (ACM) with virtual flux method (VFM) on a GPU to simulate incompressible unsteady state flow fields around a cylinder, and lattice Boltzmann method (LBM) on a GPU to simulate incompressible turbulent flows. In this study, unsteady flow fields around a circular cylinder were calculated by LBM with VFM. The history of the length of twin vortex behind a circular cylinder and the Strouhal number were compared with that of the other researchers; also, the speedup obtained by a GPU is shown.
