I want to know "an element of endwall boundary layer flows [44]" relates to "horseshoe vortices" or not? If it is not , kindly suggest ways to make it clearer.

Fig. 13 highlights the main secondary flow structures in Wells turbines such as the tip leakage vortex and horseshoe vortices, an element of endwall boundary layer flows [44], near the hub.

    It seems to mean that the tip leakage vortex and horseshoe vortices are both elements of endwall boundary layer flows. But you're right, it's not clear when 'an element' suggests a single element.

    I'm no expert in this subject, so I can't be sure, but I think it should say ' . . . elements of . . . '.

    OK, I understood.

    Is it OK?
