Study of the Large Eddy Simulation of a Circular Jet
The circular jet was numerically simulated by the developed parallel programme based on the large eddy simulation（LES） method.The LES results were compared with the experiments to check the programme and analyze the effects of the mesh scale.The results show that the mean velocity and Reynolds stress calculated by LES agree well with those measured by the experiments and can be proved reliable and precise.The results also show that the mesh scale affects the first standardized moment little but the second and third standardized moments much.So it＇s necessary to analyze the LES results with the dependence on the mesh scale to guarantee the second standardized moment precise at least when simulating the turbulent flow and turbulent combustion.
