计算流分析现在在航空航天、能源和交通技术中发挥着关键作用，为降落伞的空气动力学、地面车辆和轮胎的热流体分析以及风力涡轮机的流固耦合分析等具有挑战性的问题提供了解决方案。计算挑战包括复杂的几何形状、移动边界和界面、FSI、湍流、旋转流动和大型问题。基于残差的变分多尺度（RBVMS）、ALE-VMS和时空多尺度（ST-VMS）方法是解决计算挑战的核心方法，已经取得了相当大的成功。在核心方法的基础上，还补充了针对特定问题类别的特殊方法，如滑移界面（SI）方法、多域方法和“ST-C”数据压缩方法。我们描述了核心和特殊方法。作为使用这些方法进行的具有挑战性的计算的例子，我们提出了冲压空气降落伞的空气动力学分析，货运卡车及其后轮胎的热流体分析，以及大气边界层流动中两个背靠背风力涡轮机的空气动力学和FSI分析。
Computational flow analysis is now playing a key role in aerospace, energy and transportation technologies, bringing solution in challenging problems such as aerodynamics of parachutes, thermo-fluid analysis of ground vehicles and tires, and fluid–structure interaction (FSI) analysis of wind turbines. The computational challenges include complex geometries, moving boundaries and interfaces, FSI, turbulent flows, rotational flows, and large problem sizes. The Residual-Based Variational Multiscale (RBVMS), ALE-VMS and Space–Time VMS (ST-VMS) methods have been quite successful serving as core methods in addressing the computational challenges. The core methods are supplemented with special methods targeting specific classes of problems, such as the Slip Interface (SI) method, Multi-Domain Method, and the “ST-C” data compression method. We describe the core and special methods. We present, as examples of challenging computations performed with these methods, aerodynamic analysis of a ram-air parachute, thermo-fluid analysis of a freight truck and its rear set of tires, and aerodynamic and FSI analysis of two back-to-back wind turbines in atmospheric boundary layer flow.
