摘要
采用大涡模拟方法可以分析和计算近地阶段尾涡消散和运动规律,但模型繁琐、计算复杂。本研究基于镜像涡方法建立了形式相对简单、计算迅速的近地尾涡运动模型和消散模型,计算结果与激光雷达测量数据和大涡模拟数据的偏差都不超过5%,满足动态尾涡间隔研究的需要。
The large eddy simulation methods can be used to analysis and calculate the decay and transport rules of wake vortex in near ground phases, but it＇s too complex and difficult to use. This paper based on the image vortex method to construct the relatively simple and quickly calculated wake vortex decay and transport models in near ground phases, the results calculated by this model is similar to the large eddy simulation models and lidar measured, can be used in the dynamic wake vortex separation systems.
