The purpose of the course is to provide state-of-the-art information on physical modeling, and numerical simulation of multifluid flows. The presence of interfaces substantially increases the complexity of multifluid turbulent flows and poses a great challenge to numerical simulation. Indeed, simulations of interface behaviour require numerical methods that would ideally describe the interface motion precisely, handle jump conditions at the interface without artificial smoothing, and respect mass conservation, The methods which will be emphasised along this lecture series will concern; Large Eddy Simulation, Direct Numerical Simulation, Volume of Fluid, Level Set, and Ghost Fluid.

本课程的目的是提供最先进的物理建模和多流体流动的数值模拟信息。界面的存在大大增加了多流体湍流流动的复杂性，给数值模拟带来了巨大的挑战。实际上，界面行为的模拟需要精确地描述界面运动的数值方法，处理界面处的跳跃条件而无需人工平滑，并尊重质量守恒。沿着本系列讲座将重点关注的方法有：大涡模拟、直接数值模拟、流体体积、水平集和虚拟流体。
