PIV Measurements of Natural Convection Channel Flows with Kármán Vortex Streets

In this thesis natural convection channel flows are analysed by the use of optical-laser-speed measurements
(PIV). The investigation is divided into cases with installed bodies serving as vortex promoters
and reference cases without. The aim is to get knowledge about the velocity fields and vorticity
strength of the developing vortices. Within the investigation the channel size, the bodies geometry
and the wall temperature is varied. There are also measurements in close distance to the wall. The
collected data is analysed and used to validate CFD-Simulation data.
