Abstract

The invention discloses a complex terrain wind field simulation method and device based on WRF and Fluent coupling. Coarse resolution wind field data of a CFD three-dimensional complex terrain model is simulated through a WRF (Weather Research and Forecasting Model), a WRF wind field mesh model is established, wind field data calculated by the WRF wind field mesh model is processed, and a distancereciprocal weighting method or a three-point coplanar linear interpolation method is used to interpolate to obtain five boundary surface wind field data of the CFD three-dimensional complex terrain model. Compared with a calculation method of curve fitting, the complex terrain wind field simulation method and device are simpler and more direct, avoid large deviation of the curve fitting when thewind speed fluctuates greatly, and solve the technical problem of low accuracy of the existing complex terrain wind field simulation method.

Description

technical field [0001] The invention relates to the field of wind field simulation, in particular to a complex terrain wind field simulation method and device based on WRF and Fluent coupling. Background technique [0002] Since the 1980s, mesoscale atmospheric numerical models have developed considerably. Currently, the commonly used mesoscale model is the WRF model (Weather Research and Forecasting Model, weather forecasting model). The spatial resolution of the mesoscale weather forecasting model is usually on the order of 1 km or more, which can meet the simulation research of large regional wind fields to a certain extent; however, due to the limitation of its grid precision, it cannot capture the smaller-scale climate environment Changes and site terrain changes, especially in complex terrain areas, cannot accurately simulate complex terrain, buildings, etc., so accurate and reliable near-surface wind field characteristics cannot be obtained. [0003] The existing te...
