Abstract: | The velocity field and wall heat transfer distributions for internal flows in the presence of longitudinal vortices have been experimentally investigated. A transient method based on temperature measurement with thermochromic liquid crystals was used to obtain the heat transfer distribution behind a tetrahedral, full-body vortex generator. With the focus on the longitudinal vortices, the flow field was captured by a three-component particle image velocimetry system. Mean values as well as velocity fluctuations have been assessed. The combined investigation of heat transfer and flow field describes in detail the physical conditions. For a channel Reynolds number of 300,000 a dataset has been obtained, which can be used for validation of numerical models. |
