Influence of a Wavy Blade-End Applied in an Axial Compressor Cascade on the Secondary Flow of the Passage [PDF]
Journal of Applied Fluid Mechanics, 2022 To improve the compressor performances at variable conditions, in this research, we used numerical simulation software to analyze and discuss the effects of three kinks of a wavy blade-end on an axial compressor cascade.

A steady separated viscous corner flow [PDF]
Journal of Fluid Mechanics, 1991 An example is presented of a separated flow in an unbounded domain in which, as the Reynolds number becomes large, the separated region remains of size 0(1) and tends to a non-trivial Prandtl-Batchelor flow. The multigrid method is used to obtain rapid convergence to the solution of the discretized Navier-Stokes equations at Reynolds numbers of up to ...

The Investigation of a New End Wall Contouring Method for Axial Compressors
Applied Sciences, 2022 To further control corner separation in high-load axial compressors, this study proposes a new end wall contouring method. It defines multiple standard “surface units” with particular flow control effects and then applies a linear combination, finally ...

Research on the Influence of Inflow Conditions on the Aerodynamic Performance of a Tandem Cascade [PDF]
Journal of Applied Fluid Mechanics, 2022 We perform a thorough numerical analysis of the impact of inflow conditions on the aerodynamic performance of a tandem cascade. In particular, we investigate the effects of the incidence angle and the inlet boundary layer (IBL) thickness on the three ...

Seal leakage Flow-affected Compressor Endwall and Fillet Profiling Design: Based on Optimization and Data Mining [PDF]
Journal of Applied Fluid MechanicsIn current research of axial compressor, flow control profiling designs for corner separation often overlook the influence of seal leakage flows, whose impact grows with increasing single-stage pressure ratios. Seal leakage flow alters near-wall velocity

Investigation and Improvement of T-Tail Junction Flow Separation for a Demonstration Aircraft
Aerospace, 2022 Flow separation is easily induced at the junctions of aircraft components, and for aircraft with T-type tails, in particular, it can lead to loss of directional stability under a small sideslip angle. In the reported study, improved delayed detached eddy

The Study of the Concave Corner Flow Separation in the Hypersonic Flow.
Journal of the Japan Society for Aeronautical and Space Sciences, 1998 To clarify the action of the rudder of HSTs, a hypersonic convex flow separation was studied. In a hypersonic flow the rudder can not act efficiently because of the boundary layer separation, so that studies of that are needed. In previous studies, the hypersonic convex flow separation was not studied because the surface pressure gradient of the convex

Corner effect and separation in transonic channel flows [PDF]
Journal of Fluid Mechanics, 2011 An investigation into parameters affecting separation in normal shock wave/boundary layer interactions (SBLIs) has been conducted. It has been shown that the effective aspect ratio of an experimental facility (defined as δ*/tunnel width) is a critical factor in determining when shock-induced separation will occur. Experiments examining M∞ = 1.4 and 1.5
