Wagner, G. J.; Liu, W. K. Turbulence simulation and multiple scale subgrid models. (English) Zbl 0972.76050 Comput. Mech. 25, No. 2-3, 117-136 (2000). From the summary: The problem of modelling turbulence in CFD is due to the wide range of length scales present in a turbulent flow. The physics of these scales is examined, and the need for models of the small scale motions is made clear. A review is given of methods of turbulence modelling. These methods can be divided into two classes: Reynolds averaged Navier-Stokes models, and large eddy simulation (LES). The reproducing kernel particle method (RKPM) is then presented and proposed as a class of filters for LES of inhomogeneous turbulent flows. Important properties of the method are discussed, including the effectiveness of the RKPM reproduction as a low-pass filter.
