基于OpenFOAM的典型复杂地形流场演变
The evolution of complex terrain flow fields based on OpenFOAM
摘要
Abstract
With the depletion of resources in flat terrain,the site selection for wind farms is gradually shifting towards complex terrains.Complex terrain presents geographical conditions distinct from flat terrain,the undulating topography leads to intricate flow patterns,and the wind characteristics in complex terrains are also different.Therefore,studying the distribution patterns of flow fields in complex terrain is significant for micro-siting of wind farms and wind power prediction.This paper,based on the open-source software OpenFOAM,establishes geometric and numerical simulation models for complex terrain.It investigates and analyzes grids,boundary conditions,and turbulence models suitable for complex terrain.The reliability of the numerical model for complex terrain is compared and analyzed using real measurement data from the Askervein mountain.The paper solves the flow field distribution for typical complex terrains such as isolated peaks,plateaus,and peak clusters,studying the impact of slope and height on the flow fields in different terrains.The research reveals that different terrains satisfy the Reynolds number independence principle.In isolated peak topography,the influence of slope becomes more pronounced in the lee zone behind the mountain as the slope increases.Plateau terrain is more affected by changes in height.For peak cluster topography,the flow field development remains consistent under varying slopes and heights,with height having a greater impact compared to slope.The provided distribution ranges of flow field characteristic values in this paper can serve as a reference for wind farm micro-siting and wind power prediction in complex terrain.关键词
