Experimental investigation of pedestrian level winds using multiple measuring methods

Abstract eng:
In the project, methods for the pedestrian wind comfort determination were investigated. Few methods can be used for the qualitative and quantitative measurement of the wind condition at the pedestrian level. Pressure difference measurement by the omnidirectional Irwin probes, the Particle Image Velocimetry, the Hot wire anemometry, flow visualization by a little flags, sand spreading on surface around the building model, were used during solving this project. The Irwin probes are most frequently used for the pedestrian wind comfort measurement. The velocity calibration of the Irwin probe isn’t trivial so other methods were used for its verification. In this contribution the comparison of all mentioned methods was described.
