| 摘 要： | INTRODUCTIONLarge- eddy simulation ( LES) method is apowerfull tool in numerical simulations of turbu-lence. On the other hand,lattice Boltzmannmethod( LBM) is a new method in computationalfluid dynamics ( CFD) ,especially when used inlarge scale parallel applications.Therefore it isuseful to build the dynamic SGS model intoLBM.In this paper the new method of dynamicSGS model with LBM is described in detail andsome results using the method to numericallysimulate the two and three…
