Embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings.
The present invention is a kind of field of turbulent flow analogue means tested for Structural Wind Engineering, and the device is by using coming flow field
Bottom surface bloats angled air-flow to simulate field of turbulent flow.
As Figure 1-3, the device includes escape pipe 1, air cavity 2, air inlet 3, air pump 4, structural model 5 and pedestal 6, institute
The inside for the pedestal 6 stated is provided with air cavity 2, and the escape pipe 1 being arranged on pedestal 6 communicates air cavity 2 and the exterior space of pedestal 6.Base
Air inlet 3 is connected with air cavity 2 inside seat 6, the connection air pump 4 of air inlet 3, the air pump 4 is arranged on the inside of pedestal 6.
The need for actual field of turbulent flow, air pump 4, air inlet 3 and the escape pipe 1 of varying number are set, and escape pipe 1 exists
Tilt adjustable section in air cavity 2.Adjustable escape pipe 1 makes the air-flow of ejection at a certain angle with coming flow field, so
The air-flow of ejection is superimposed with to flow, the turbulent performance of random pulse that just can be in down wind and beam wind to needed for simulating, is realized
Effective simulation to wind field residing for engineering structure.
In order to preferably simulate engineering structure, the present invention replaces engineering structure to carry out mould using structural model
Intend.The structural model 5 of replacement is arranged on the outer surface of pedestal 6.
In the present invention, all external air pumps 4 of air inlet 3 can continuously work, and also variable ratio frequency changer works, and sprays escape pipe 1
Air-flow there is continuity or pulsating nature.
