Influence of expansion corner on the interaction of dual separation zones

open access: yesAIP Advances, 2022
The complex shock waves/boundary layer interaction is an important problem in inlets, which induces the interaction of multiple separation zones and has attracted experts’ attention gradually.

Fish Scale-Inspired Flow Control for Corner Vortex Suppression in Compressor Cascades [PDF]

open access: yesBiomimetics
Corner separation at the junction of blade surfaces and end walls remains a significant challenge in compressor cascade performance. This study proposes a passive flow control strategy inspired by the geometric arrangement of biological fish scales to ...

Numerical Study on the Corner Separation Control for a Compressor Cascade via Bionic Herringbone Riblets

open access: yesAerospace
Bionic herringbone riblets are applied to relieve the flow near the blade endwall in a linear compressor cascade under the incidence angle of −4° to 6° at a Reynolds number of 382,000.

Identification of corner separation modelling in axial compressor stage [PDF]

open access: yesE3S Web of Conferences, 2020
The paper presents a study of corner separations in hub to blade region at various operation conditions towards compressor stall. It is known that for compressor flows with low or none separations computation fluid dynamics with RANS methods work quite ...

Corner Separation Control by Boundary Layer Suction Applied to a Highly Loaded Axial Compressor Cascade

open access: yesEnergies, 2014
Control of corner separation has attracted much interest due to its improvement of performance and energy utilization in turbomachinery. Numerical studies have been performed under both design and off-design flow conditions to investigate the effects of ...

The Unsteady Topology of Corner Separations

open access: yesJournal of Turbomachinery, 2021
As an 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 understand whether a particular flow structure in the ...

Effect of compound lean blades on separation structures in high loaded compressor cascades under high subsonic condition

open access: yesFrontiers in Energy Research, 2022
Three-dimensional separation is an inherent flow feature in the blade-end corner of compressors passage, which is a primary source of entropy generation and loss.

Once again on the supersonic flow separation near a corner [PDF]

open access: yesJournal of Fluid Mechanics, 2002
Laminar boundary-layer separation in the supersonic flow past a corner point on a rigid body contour, also termed the compression ramp, is considered based on the viscous–inviscid interaction concept. The ‘triple-deck model’ is used to describe the interaction process.

Optimization of Sweep and Blade Lean for Diffuser to Suppress Hub Corner Vortex in Multistage Pump

open access: yesMachines, 2021
The bowl diffuser is the main flow component in multistage submersible pumps; however, secondary flow fields can easily induce a separation vortex in the hub corner region of the bowl diffuser during normal operation. To explore the flow mechanism of the
