Abstract

The invention discloses a double test section direct current gust wind tunnel. The gust wind tunnel comprises an exit section, a power section, a diffusion section, a first test section, a contractionsection, and a stabilization section. One end of the power section is connected to the exit section connected to the outside world. The other end of the power section is connected to the diffusion section. One end of the first test section is connected to the diffusion section, and the other end is connected to the contraction section. One side of the contraction section is connected to the stabilization section. The diffusion section is provided with a first current adjusting section. A second test section is arranged between the exit section and the power section. A backflow section is arranged between the power section and the second test section. The two ends of the backflow section are provided with second current adjusting sections. The side wall of the backflow section is providedwith an opening and closing door. In two test periods, testing can be performed simultaneously, and the second test period can be closed according to an actual demand.

Description

technical field

[0001] The invention relates to a gust wind tunnel experimental device, more specifically, it relates to a direct current gust wind tunnel with double test sections. Background technique

[0002] Simply put, a wind tunnel is a specially designed long-shaped pipe, in which a power system (motor and fan) generates an air flow that can be controlled freely by humans, and is used to simulate the flow of air when objects move in the air. Phenomena, the situation of objects under force, the phenomenon of air flow around certain fixed objects, and the migration and diffusion of smoke in the air, etc. ".

[0003] Boundary layer wind tunnels are playing an increasingly important role in the research of wind engineering. The boundary layer wind tunnel has the ability to simulate the flow of the atmospheric boundary layer, and can provide technical support for the study of the diffusion law of atmospheric pollutants and the safety design research of many other unique s...
