Studies on the Flow of Axisymmetric Radialwise Wall Jet on the Impinged Wall by the Annular Impinging Jet

抄録

Flow patterns for a self-preserving region on the axisymmetric radialwise wall jet on the impinged wall were experimentally studied. Denoting a distance H between annular nozzle and impinged wall and the corresponding critical distance Hc, it was ascertained that flow patterns for the region of H>Hc were similar to those of circular impinging jet. On the other hand, it was ascertained that flow patterns for the region of H<Hc might be represented by two new parameters defined experimentally in this study.
