This paper presents the results of an experimental study on the deflection and reattachment of a radial turbulent wall jet through two comparatively wide-spaced parallel disks, in the presence of a lateral control flow. The main content of this report concerns the effects of various opposite wall heights and control flow rates on the flow properties at and after the reattachment point on the wall surface. A flow field was divided into five regions. The changes of the maximum jet center velocity, the jet half-width and the turbulence at the velocity maxima, and also the deflection of the jet center axis in each region, depended mainly on the combination of the opposite wall height and the control flow rate. Further, the limiting position in which the wall jet flow pattern might be maintained was examined.
