湍流数值模拟方法及其特点分析

The methods of turbulent numerical simulation and analysis of its characteristics

结合近年来国内外学者的研究,着重从基本思想、基础理论等方面对湍流数值模拟进行了特点比较及适用性分析,湍流数值模拟方法仍处于不断的完善与探索阶段,通过分析,文章最后指出了今后可能获得突破性进展的复杂湍流探索方向。

Three methods of turbulent numerical simulation are summarized in paper： Direct Numerical Simulation （DNS）, Reynolds Averaged Navier - Stokes （RANS） and Large Eddy Simulation（LES） . Their characteristics and applicability are analyzed and compared mainly in basic conceptions and theories according to the researchers studies in the last years. The conclusions will be helpful for study of turbulence. The methods of turbulent numerical simulation are still being groped now, so the research directions that will obtain salient developments of turbulence in the future are given in the end.
