tunnel erosion
1.A set of software system to carry out data acquisition,analysis and process of wind tunnel on the general-purpose computer by means of theories of modern test technologies and ideas of virtual instruments based on configuring the hardware test system of aerodynamic characteristics of portable erosion wind tunnel making use of LabWindows/CVI was developed.
2.The erosion technique in boundary layer wind tunnel and meteorological data of Chaoyang Weather Station are used to study the wind environment of CBD. The results show that (1) when it blows strongly northwesterly wind in the winter and the spring, Beaufort number 8 wind will occur 5.0 times in the areas around the tall buildings in CBD, which influences the safety of pedestrians.
