Present state of art on pulsatile flow theory -: (Part 2:: Turbulent flow regime)

In this paper, the studies on turbulent pulsatile flows conducted up to now are presented as an extension of a previous paper dealing with laminar and transitional pulsatile flows. Turbulent boundary layer flows with a periodic free-stream, theoretical and experimental investigations on the structure of turbulent pulsatile flows, available classifications in turbulent pulsatile flows and both experimental and theoretical studies on frictional losses in turbulent pulsatile pipe flows are the basic headings discussed in the paper. Several basic gaps on the manner are determined and listed as further research topics.
