摘要
Abstract
For the turbulent flows of the open-channels, the effects offactors of calculational mesh, the sizes of computational domain, SGS models and Reynolds numbers on the prediction precision of large eddy simulation(LES) are discussed. The results indicate that the prediction precision of LES is deeply affected by the sizes and the matching of mesh, even for those simple turbulent flows. In practice , the above factors should be considered.关键词
