Abstract

A study has been made of the attachment of a radial turbulent jet flow to an adjacent offset disc plate. Mean velocity and turbulence together with pressure distributions were measured, and the effects of diameter and width of nozzles, and also of distance of nozzle center plane from offset plate on flow pattern were investigated. Length and average negative pressure in the region of recirculating flow were examined. The results were compared with those obtained for two-dimensional attaching jet flow. An oil film flow visualizing technique was also applied to determination of the flow pattern, and the results were compared with those assumed from measured velocity and pressure distributions. Position of maximum value of maximum jet center velocity, and also agrees well with the position of jet attachment point obtained by the flow visualization.
