Wind deflection angle continuously adjustable torsion wind profile wind tunnel test passive simulation method

Abstract

The invention discloses a wind deflection angle continuously adjustable torsion wind profile wind tunnel test passive simulation method, and belongs to the field of civil engineering. A single-angle continuous torsion guide plate manufacturing method includes: firstly, manufacturing a single-angle continuous torsion guide plate, which is formed by overlapping a wood plate and a plurality of horizontally-arranged batten plates, wherein a torsion angle exists between every two adjacent batten plates, and the torsion angle of a target wind section is achieved by deflecting the batten plates at different positions; realizing an integral torsion guide plate system; debugging a torsional wind deflection angle of a torsional wind profile guide plate system; checking whether the torsional wind profile conforms to a target torsional wind profile or not through a wind speed sensor, and if yes, performing a subsequent wind tunnel test on the torsional wind profile effect; and if the torsional wind profile and the target torsional wind profile are inconsistent, adjusting the bottom wind deflection angle and turbulence by increasing the number of rough elements and adjusting the placement angles of the rough elements. The torsional wind profile can be accurately simulated.

Description

Technical field [0001] The present invention belongs to the field of civil engineering, which specifically involves a passive simulation method of a wind-independent adjustable torsional wind profile wind tunnel. Background technique [0002] The hill hills are not only changed through wind speeds, but also change the wind environment by changing the wind. As a result, the wind profile near the category terrain exhibits a highly changed wind direction, which is often referred to as (terrain drive) twist contour. The tower building (such as business districts or residential areas) is not negligible by reverse wind profiles, mainly two impacts: a city's wind environment is important, affecting pedestrian comfort, etc., and urban wind environment Corrected with round-saving velocity, such as transient wind speed, turbulence and wind angle, etc .; which is for elongated flexibility or with eccentric shaped buildings, torsional wind profiles have formed an asymmetric wind pressure on ...

AI Technical Summary

Problems solved by technology

It is true that multiple twisted (torsion) angles can be obtained by manufacturing multiple sets of vane systems (deflection deflector systems), but it is almost impossible to achieve in wind tunnel tests, because multiple sets of vane systems require cumbersome installation and disassembly and wind field Debugging process
