课程简介（教工部数据）
大涡模拟计算方法是计算流体力学领域最新出现的紊流数值计算方法之一，其通过求解水、气中的大尺度流动、模拟小尺度影响，而兼顾了紊流计算的精确性和工程应用的经济性。近几十年来，大涡模拟计算方法已经越来越多地用作解决水利和环境工程问题的重要工具，如水中泥沙输移问题、水和大气中的污染物输移问题。本课程分为三部分内容：1）详细讲述大涡模拟计算方法的基本原理，2）系统性地综述了近几十年大涡模拟技术在水力学领域的应用成果，3）学习开源大涡模拟计算商业软件。使学生能够了解一种计算流体力学原理方法、开阔科学研究的视野、并掌握一门实用数值计算软件。
The Large Eddy Simulation (LES) method is one of the latest turbulence numerical calculation methods in the field of computational fluid dynamics. It solves the large-scale flow in water and air and simulates small-scale eddies, while taking into account the accuracy of turbulence calculation and engineering applications and economy. In recent decades, LES has been increasingly used as an important tool to solve water conservancy and environmental engineering problems, such as the problem of sediment transport in water, the transport of pollutants in water and the atmosphere.This course is divided into three parts: 1) The basic principles of the large eddy simulation calculation method are described in detail; 2) The application results of the large eddy simulation technology in the field of hydraulics are systematically reviewed in recent decades; 3) Commercial software for LES. It is designed to enable students to understand a principle and method of computational fluid dynamics, to broaden the horizons of scientific research, and to master a practical numerical calculation software.
