摘要
详细讨论了湍流中颗粒运动的直接数值模拟 (DNS)和大涡模拟 (LES)方法。尤其是研究了大涡模拟的子网格模型。通过模拟 ,最后得到大涡模拟 (LES)
Dirrct numerical simulation(DNS) and large-eddy simulation(LES),which are been developing to model the turbulent flows,are discussed in details.Especially the formulation of LES and subgrid-scale models of LES are investigated.Finally,the large-eddy simulation(LES)is suggested as a suitable method to simulate the motion of particles in turbulent flows.
