Flow separation and reattachment
WebApr 29, 2024 · This occurred because the characteristics of the deviated flow became similar owing to the boundary layer that formed on the roof surface after reattachment . Comparing the two cases, the absolute value based on f / D = 0.05 was slightly smaller at the normalized diameter of 0.75, as it was affected by the separation of the deviated flow. Web1 day ago · A quantitative analysis illustrating salient features of a Laminar Separation Bubble (LSB), its transition forming coherent structures, and associated heat transfer has been performed on a flat plate for varying free stream turbulence (fst) between 1.2% to 10.3%.

WebDuring the equilibrium phase, flow separation occurs at the leading edge of the cusp with reattachment at the wall of sinus. At this point, flow splits into two streams at each valve cusp. Part of the flow is directed into the sinus pocket behind the valve cusp, forming a vortex along the valve cusp before re-emerging in the main stream in the ...
