“…In general, there are some slight disagreements in the different flow models that have been proposed but, for the most part, these flow models, which are primarily based on uniform inlet profiles except for the turbulent endwall boundary layers, agree on the existence of the leading edge and passage vortices. Experimental flowfield data presented by Bailey [6], Moore et al [7], Gregory-Smith and Cleak [8], and Kang et al [9] have all quantified some aspects of the secondary flows. All of these studies, however, have had an inlet boundary condition of a uniform flow except for a turbulent endwall boundary layer such as that shown in Fig.…”
