ALGEBRAIC MODELLING OF LARGE EDDY SIMULATION AND ITS APPLICATION

摘要

An algebraic modelling o?large eddy simulation (LES) has been proposed and discussed in detail. Its basic idea and application to numerical simulation of turbulence in a straight channel and a curved channel are presented. Primary computational results show the feasibility of this modelling. It is our hope that this modelling) if further improved, will be useful for the numerical simulation of more complicated turbulence.
