Flow in the initial segment of a tube with a sharp leading edge
- 26 Downloads
Visualization is used to study the three-dimensional structure of detached flow in the initial segment of a circular straight tube with a sharp 90°-angle leading edge. It is demonstrated that at Re > 75.103 there is no attachment of the separated shear layer, while a secondary flow develops at the wall.
