Large eddy simulation theory and its application

A review is made on the basic theory and development process of the large eddy simulation (LES) and the current situation and prospects of its application, and an introduction is given to the simulated results of separating phenomena in flows around square cylinder and the interaction between jets and linear waves by use of the LES theory. The research shows that the LES theory has powerful capacity in simulation of micro-structures of turbulent flows, and can be widely applied to the solution of real engineering problems.
