摘要
在分析飓风对输电网络影响的机制上,采用流体工程仿真软件FLUENT对某人工环境模拟实验室的风洞试验进行三维数值模拟,获得了小型人工气候室内的三维流场特性和风速参数,并分析考察了导流板和导风板对子试验区流场均匀性的影响。研究结果表明,合理增加导流板和导风板数量可提高风速均匀度以满足实验模拟要求。研究工作为人工环境模拟实验室的搭建和风洞试验流场均匀性的进一步改进提供一定的理论依据。
Based on the analysis of influence mechanism of the hurricane on the transmission network, a 3-d numerical simulation based on the engineering fluid simulation software named FLUENT was conducted to simulate the wind tunnel test of artificial atmospherie phenomena simulator. The characteristics and parameters of the 3 - d flow field in the phytotron were simulated. And the influence of bend guide plate and straight air deflector on the uniformity of the flow field of testing zone was investigated. The results show that the increase of the number of bend guide plate and straight air deflector could improve the uniformity of the flow field to meet the requirement of the simulation. The work is helpful for the construction of artificial environment simulation laboratory and the improvement of the uniformity of the flow field of the wind tunnel test.
