摘要
为了提高微风发电的效率,文中基于文丘里效应设聚风装置.低速风通过对结构的优化收集更大风量来流提高来流风速.针对聚风装置进口长度、角度和出口长度、角度等主要结构参数做组合设计,采用三维数值模拟方法计算不同聚风装置的喉口部位的速度、压力和聚风比,对比分析结果找到最优的聚风装置结构参数,结果发现:优化后可有效提升来流风速.通过分析聚风装置结构和流场变化,揭示流体对聚风装置结构的影响机理.
Abstract
In this article,in order to improve the efficiency of breeze power generation,an air collector is designed based on the Venturi effect.This breeze air collector collects more air volume by optimizing its structure to improve the flow wind speed.It is shown that the flow wind speed can be effectively improved by comparing and combining different main structure parameters,such as the length and angle at the air collector's inlet and outlet.The three-dimensional numerical simulation method is used to calculate the speed,pressure,and air-collecting ratio at the throat of different air collectors.Through a series of comparison and analysis,the air collector's optimal structural parameters are worked out.It is shown that after optimization,the flow wind speed has greatly improved.By analyzing the air collector's structure and flow field changes,the influence of the fluid on the air collec-tor's structure is revealed.
