Beneficial Effects of Guide Fins on Corner Separation

open access: yesVolume 13A: Turbomachinery — Axial Flow Fan and Compressor Aerodynamics, 2023
Abstract Corner separation is a major phenomenon limiting the operability of aeronautical compressors. Passive control devices such as guide fins are envisioned to reduce its deleterious effects. In this paper, guide fins are optimized to reduce the total pressure losses downstream of a subsonic compressor cascade (M = 0.11, Re = 3.2 105,

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.

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

Influence of Ellipsoidal Dimple Column Number on Performance of Highly-loaded Compressor Cascade [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2023
The impact of the column number of ellipsoidal dimples on a highly-loaded compressor cascade (NACA65-K48) under design conditions was investigated by using a numerical simulation method.

Toward the Utilization of 3D Blading in the Cantilevered Stator from Highly Loaded Compressors

open access: yesApplied Sciences, 2023
Three-dimensional blading is an efficient technique in compressor aerodynamic design, and its function mechanism in the cantilevered stator needs to be addressed. This paper focuses on the sweep and dihedral in the cantilevered stator and seeks to expose

Global Visualization of Compressible Swept Convex-Corner Flow Using Pressure-Sensitive Paint

open access: yesAerospace, 2021
This study used pressure-sensitive paint (PSP) and determined the surface pressure distributions for a compressible swept convex-corner flow. The freestream Mach numbers were 0.64 and 0.83.

Effects of pulsed endwall air injection on corner separation and vortical flow of a compressor cascade

open access: yesEngineering Applications of Computational Fluid Mechanics, 2022
Air injection is an effective method to eliminate flow separation and improve blade loading in compressors. In existing studies on unsteady air injection, achieving a better control effect than steady injection with lower injection consumption is a major
