Background technique
Wind-tunnel is the pipeline for generating man-made airflow, and main task is to provide various velocity interval indoors modeling tests must
The aerodynamic environment of palpus, and the region of air-flow Uniform Flow is formed in test section.
When blowing air over ground, roughness element such as grass, crops, trees and house on ground can all generate friction resistance to wind
Power, to form up big and down small wind profile and up-small and down-big turbulence intensity profile.For this to by earth's surface frictional resistance
The atmosphere of influence is referred to as atmospheric boundary layer.Building on ground is in atmospheric boundary layer, so grinding in wind-tunnel
When studying carefully effect of the wind to building, other than model to be met is similar to prototype, correct simulation of atmospheric boundary layer stream is also wanted
, this is mainly completed by wedge, roughness element technology.Wedge is miscarried raw vortex using the separation of its plate windward, is met
The width of aerofoil determines the size and turbulence pulsation intensity of vortex, while the blockage ratio of plate successively decreases along height windward, can produce
The wind profile of approximately linear.
It carries out needing to simulate the Air Flow In The Boundary Layer for meeting requirement of experiment before wind tunnel experiment, presently mainly pass through
The position of wedge and roughness element is moved repeatedly to adjust the wind field in wind-tunnel.Traditionally, spoiler is mounted by means of bolts on
On wedge, when adjusting, needs manual teardown and reinstalls spoiler, adjusts that wedge is relatively complicated, and required time is longer.
