“…Therefore, many reports have appeared about the plane wall jet and the effects of streamwise curvature on the velocity and fluctuating velocity distribution have been studied (1) - (13) . The effect of a nozzle width on the flow characteristics was investigated by Shakouchi and Onohara (10) and a comparison was made between a cylindrical wall jet and its plane equivalent by Neuendorf and Wygnanski (12) . However, most of papers deal with the case of a side wall only on one side and the effect of a boundary condition at the nozzle exit on the flow is still unknown.…”

Flow characteristics of a two-dimensional jet with side walls have been studied experimentally. Three kinds of cylindrical walls and a flat wall were provided as the side walls, and they were combined and attached to a nozzle. Nine types of side wall conditions were investigated. Velocity was measured by a hot-wire probe and the separation point was measured by a Pitot tube. Mean velocity profiles, the growth of the jet half-width, the decay of jet maximum velocity, and the attachment distance were clarified. When cylindrical walls with different radii are installed, the flow pattern changes markedly depending on the velocity of the jet. A striking increase in the jet half-width is related to the separation of flow from the smaller cylindrical wall just behind the nozzle.

“…For the cylindrical wall jet, the attachment distance increases with an increase in the jet velocity (10) . When two cylindrical walls are installed, the attachment distance shows a local maximum value and then decreases with an increase in the jet velocity.…”
