为了有效收集风流，本文提出了扩散体型挡风坝集风系统，确定了扩散体挡风坝模型的尺寸，通过Fluent软件模拟了不同入口风速时，扩散体坝体截面中心点至地面不同高度点风速，并确定了风速增大倍数。在此基础上，开展了基于风洞的扩散体挡风坝集风实验，结果表明：扩散体挡风坝数值模拟结果与风洞实验结果基本一致，风速均增加近0．5倍左右，挡风坝集风效果明显。研究结论对挡风坝风力发电系统的工程可行性和经济效益具有重要的理论和现实指导意义。

In order to effectively collect airflow ,the diffusion wind dam is presented and the dam dimension is determined , the Fluent software is applied to simulate airflow velocity of different height on the condition of various inlet airflow velocity and the increases in multiples of airflow is obtained .Then airflow collection experiment of diffusion system wind dam is con-ducted based on wind tunnel and the results show that the results of experiment and simulation are consistent ,the velocity is nearly 0 .5 times around and the collection effect is obvious .The conclusions are significant and directive to wind dam power generation .
