风力发电机塔筒结构在坡地上的风压数值模拟
Numerical Simulation of Wind Pressure on the Wind Turbine to Werstructure on the Sloping Field
摘要
Abstract
In order to study the influence of different terrain on wind power generator when wind come through,and take the wind power generators of Baiyunebo,in Inner Mongolia,as study object. The models of the wind turbine tower on the slopes of 15 ° ,30 ° ,45 ° are established by ANSYS finite element software,the relationship of wind pressure value between plains and mountains is deduced by the distribution of wind pressure coefficient around the tower when winds come through, the characteristics of the flow field around the tower and the recommended value of climbing increment coefficient are obtained. By analysis,wind pressure and wind speed will increase with the increase of slope,and on the surface of the tower,the wind pressure coefficients distribution in the windward side is more dense than the leeward side,the maximum positive pressure coefficients locate in the 0° position,and the minimum negative wind pressure coefficient locate in the 90°and 270° positions on the side. The research results will provide a reference for the design of the wind power generator on different landforms.关键词
