It is discharged by special-shaped discharge pipe, the inner wall of the abnormity discharge pipe is using the curved surface seamlessly transitted, the air intake of special-shaped discharge pipe
Outlet air end for a rectangular opening identical with the tip dimensions of rectangular duct, special-shaped discharge pipe is a circular port, circular port
Area and rectangular opening area 5% of difference no more than smaller area in the two, define the circular port center of circle and rectangular opening be diagonal
Line between line center is the central datum line of special-shaped discharge pipe, and the central datum line distinguishes institute with circular port and rectangular opening
Two planes it is vertical, and the central datum line length satisfaction can make it is most short between rectangular opening quadrangle and circular port
Line and central datum line angle β size be 7.5 ° to 15 °.
Preferably, the area equation of the area of the circular port and rectangular opening.
Preferably, the outer wall of the special-shaped discharge pipe seamlessly transits song to be identical with the inner wall shape of special-shaped discharge pipe
Face.
Preferably, the special-shaped discharge pipe is used is made of the method for one piece of prefabricated steel cans.
According to above-mentioned technical proposal, the beneficial effects of the invention are as follows：
The present invention is equipped with special-shaped discharge pipe in the rectangular duct end of wind turbine, and one end of special-shaped discharge pipe is rectangular opening, and one end is
Circular port, tube wall are then that three-dimensional flow theory is utilized, smoothed from rectangular opening to circular port after CFD analyses and CAD fittings
The curved surface crossed；Special-shaped discharge pipe is from rectangular opening to circular port transitional structure, through CFD simulation calculations and it was verified that can be right
Air-flow in special-shaped discharge pipe carries out rectification and diffusion can make compared with existing wind turbine is from the end outlet air of rectangular duct
The air-flow flowed out from circular port is more uniform, so that wind turbine outlet air is more stablized, and can reduce wind turbine under identical operating condition
The power of consumption enables burner normally, efficiently to work to improve the efficiency and performance of wind turbine.
