抄録

An experimental study is presented which deals with the deflection and reattachment of an axisymmetric radial turbulent wall jet discharged from a cylindrical nozzle onto an adjacent disk plate, in the presence of a lateral control flow. Mean and turbulent velocities were measured with a hot-wire anemometer, while static pressure distributions along the wall surface and across the jet flow were measured by means of static pressure probes. The effects of various control flow rates (ratio of the control flow rate to the main jet flow rate) on the jet flow properties in the region before a reattachment point were investigated. The mean negative pressure in a recirculating flow region, the position of the reattachment to the wall surface, the changes of the maximum jet center velocity, the jet half width, and the turbulence intensities at the velocity maxima depend mainly on the control flow rate.
