This paper is concerned with the results of an experimental study on the control of a radial turbulent wall jet through two comparatively wide-spaced parallel disks. Distributions of mean velocity, turbulent velocity and wall static pressure were measured with the aid of a hot-wire anemometer and a disk-type pressure hole, respectively. The effect of the opposite wall height (distance of the opposite wall surface form the nozzle center plane) on the flow pattern through two parallel disks was investigated. 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, depended mainly on the opposite wall height. Further, the limiting position in which the wall jet flow pattern might be maintained was examined.
