A study has been made of a flow at and after an attaching point of a radial attaching jet flow on an adjacent offset disc plate. Mean velocity, turbulent velocity and static pressure distributions were measured. The effects of the diameter and width of nozzles, and also of the distance of nozzle center from an offset plate on flow pattern were investigated. A flow field has been divided into three regions : recirculating flow region formed near a nozzle outlet, transitional region where jet center velocity increases downward, and wall jet flow region where jet center velocity decreases with distance. Changes of jet center velocity, thickness of inner layer and jet half width in the wall jet flow region along the flow were measured, and it was found that these results agreed well with those for the radial wall jet flow.
