Separation and wakes over three-dimensional bodies
… focused in the neighborhood of three-dimensional separation. The Vortex-Lattice method was employed to calculate the inviscid flow and the development of separated vortex sheets over a prolate spheroid. An approximate-method based on the assumption of local similarity was used to solve the …

Pressure signature in adverse-pressure-gradient wall bounded turbulent flows
… in wall-bounded adverse pressure gradient turbulent flows. For this purpose, the experimental work has been carried out towards further understanding of this class of flows, especially when the pressure gradient is increasingly adverse. Adverse pressure gradient turbulent flows and …

Reduction of Helmet Buffeting in Open Cockpit, Single Seat Race Cars
… showed that the sources of buffeting are turbulent separation at the rear of the helmets as well as unsteady flow in the region between helmet and headrest. Best improvements were made by preventing separation on the rear of the helmet through the introduction of a fairing, and by limiting …

Potential flow solution and incompressible boundary layer for a two-dimensional cascade
… rather important conclusion may be drawn that turbulent separation, if it occurs at all, takes place close to the rear stagnation point of the blade for the applied range of upstream velocities. Another conclusion may be drawn from the displacement thickness distribution in that the flow values …

Shock oscillation mechanisms of highly separated transitional shock-wave/boundary-layer interactions
… is higher blade loading, leading to larger separations. These conditions combined induce a shock oscillation with frequencies approximately matching the blade's natural structural frequencies. This resonance causes excitation and vibrations, which, if not mitigated, can lead to fatigue and …

Concurrent Aerodynamic Shape / Cost Design Of Magnetic Levitation Vehicles Using Multidisciplinary Design Optimization Techniques
… Criterion to determine the location of the turbulent separation, and the vorticity conservation condition to determine the strength of the shed vorticity. The continuous vortex sheet better matches the mechanics of the flow than discrete singularities and therefore better predicts the ground …

The Unsteady Topology of Corner Separations
… axial compressor is throttled three-dimensional separations develop in the corners between the blades and annulus endwall. Surprisingly, little is understood about the unsteady topology of these separations. One of the problems with studying corner separations is that it is often difficult to …
