Flows Generated by the Impingement of a Jet on a Rotating Surface: Part II—Detailed Flow Structure and Analysis

Abstract

In Part I of this investigation, the basic flow patterns resulting from the interaction of a turbulent jet and a rotating disk flow were presented paying particular attention to mean and turbulent velocity fields around the jet impingement point on the disk and the flow patterns above the disk in the absence of the jet. The latter was used as a base flow pattern, on which the influence of the jet impingement could be assessed. In Part II, further details of the jet/disk flow interaction problem are discussed in the context of potential turbomachinery cooling applications and previous experimental results.
