Abstract
This paper presents the result of an experimental study on a reattachment of a radial turbulent jet discharged from a cylindrical nozzle onto an adjacent disk plate. The flow on the side wall are visualized by oil film and surface tuft methods, and the velocity field near the wall (forward flow fraction, power spectra and time-space correlations of the fluctuating velocity) are measured by hot-wire probes. The reattachment positions are distributed concentrically and the flow is axisymmetry. However, the flow around the reattachment positon periodically switches its direction relatively.
