| Abstract: | 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. |
