Comparative Study of the Performance Improvement of an Axial Compressor with a Micro-Vortex Generator and a Suction Slot [PDF]
Flow control methods have been gradually applied to improve the flow field characteristics of axial compressors. However, most of the current research is focused on the cascade, and few studies have taken a compressor as the research object. Therefore, a

Both the compressor performance and the 3D flows inside the stator passage are significantly impacted by the stator hub gap. The interplay between leakage flow and corner separation within a cantilevered stator of a highly loaded, low-speed axial ...

Separation Control for a Transonic Convex Corner Flow Using Ramp-Type Vortex Generators
A flap can be used to control wing camber and as a high-lift device. A convex corner is a simplified model of the upper surface of a flap. At transonic speeds, shock-induced boundary layer separation (SIBLS) occurs at greater freestream Mach numbers and ...

The Effect of Trailing Edge Clearance in Suppressing Hub-Corner Stall
Hub corner is a high-loss area located within in the blade passages of turbomachinery. It is well known that flow separation and vortex development in this area directly affects, not only energy loss and efficiency, but also the stability of axial ...

A steady separated viscous corner flow [PDF]
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
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 ...

Influence of a Wavy Blade-End Applied in an Axial Compressor Cascade on the Secondary Flow of the Passage [PDF]
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.

Seal leakage Flow-affected Compressor Endwall and Fillet Profiling Design: Based on Optimization and Data Mining [PDF]
In 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
