Abstract

The invention discloses a suction gust wind tunnel with a porous turning device. The suction gust wind tunnel comprises a settling chamber, a contraction section, a test section, a diffuser section, apower section and an exit diffuser section which are connected in sequence. The technical points include the porous turning device is arranged for controlling air flux to change air flow rate entering the test section from the power section so as to form gust; rate of variation of gust in the test section is changed by controlling turning rate of a porous turning plate. The gust wind tunnel can generate gust in high or low frequency.

Description

technical field

[0001] The invention relates to a gust wind tunnel experimental device in the technical field of wind engineering, in particular to a suction gust wind tunnel with a multi-hole rotating device. Background technique

[0002] Simply put, a wind tunnel is a specially designed long pipe, which generates an airflow that can be controlled freely by the power system (motor and fan) inside it, and uses it 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] Air pollution, also known as air pollution, according to the definition of the International Organization for Standardization (ISO), air pollution usually refers to certain substances entering the atmosphere due to human activities or natural processes, presenting sufficient concentrations, reaching sufficient time, and Phenomena that a...
