Abstract:
Planar jets are used in various applications, such as drying, heating, cooling, and dust removal. In particular, the flow injected into a container has been reported by many researchers because it is used for heating in the container manufacturing process. The authors have investigated the effect of nozzle offset distance on the behavior of planar jets injected into a rectangular container through experiments and numerical analysis. Although the planar nozzle, which was close to the container wall, did not allow the jet oscillation, the planar jet reached the bottom of the container. The present paper describes the results of the effect of the shape of the nozzle exit brim, which is installed at the nozzle exit, on the flow characteristics in a rectangular container were experimentally investigated using the particle image velocimetry (PIV) system. It is found that the long horizontal plate of the nozzle brim and the long vertical plate of the L-shaped nozzle brim are effective to attach a slit jet on the wall due to the Coanda effect, and the planar jet reaches near the bottom of the container.
