Abstract

By use of various lengths of shroud an experimental study was made of a partially confined jet to examine the transition between the flow configuration for a free jet to that of a confined jet. An examination of the reattachment pressure distributions and the parameters at the entrance of the abrupt channel expansion was made. A smooth transition of mean flow quantities was found to occur in the transition from a free jet to a partially confined jet and then to a fully confined jet. The distance to reattachment was measured for various shroud lengths and shown to exhibit an asymptotic value which was Reynolds number dependent. Associated with this maximum reattachment length was a maximum pressure recovery factor. The range of Reynolds numbers - based upon the jet diameter - for the present study was 80,000 to 280,000.
