Compilation of Vortex Filament of Arch Vortex in Wake of Cooling Tower Model

Abstract

This paper deals with flow around a bluff body of hyperboloid shape. It consists of results gathered in the course of research by means of Particle Image Velocimetry (PIV) and Hot-Wire Anemometry (HWA). The experiments were carried out in a range of Reynolds numbers from 42000 to 52000. A model was measured in a wind tunnel with a modelled atmospheric boundary layer. The model was tested in a subcritical range of Reynolds number and various planes in a wake of the model were captured with the intention of getting a picture of an arch vortex, moreover the HWA system was used to get the frequencies of the vortex shedding.
