Corner Separation Dynamics in a Linear Compressor Cascade

Journal of Fluids Engineering, 2016
This paper considers the inherent unsteady behavior of the three-dimensional (3D) separation in the corner region of a subsonic linear compressor cascade equipped of 13 NACA 65-009 profile blades. Detailed experimental measurements were carried out at different sections in spanwise direction achieving, simultaneously, unsteady wall pressure signals on ...

Numerical Investigation of Corner Separation on Compressor Cascade

Volume 6A: Turbomachinery, 2013
This paper studied the effects of suction surface corner separation on the aerodynamic performance and the effects of the blade parameters on suction surface corner separation in rectangular cascade. Corner separation alters the static pressure distribution on the suction surface, establish a C-Shape pressure distribution along spanwise, compared with ...

THE ANGLE OF SEPARATION IN STOKES FLOW NEAR A SHARP CORNER

The Quarterly Journal of Mechanics and Applied Mathematics, 1984
\textit{H. K. Moffatt} in a well known paper [J. Fluid Mech. 18, 1-18 (1964; Zbl 0118.205)] considered the flow in a planar corner and showed that in some cases there is an infinite succession of eddies dying away in strength as the corner is approached.

Incipient Separation Near Corners

2017
AbstractChapter 4 analyses the transition from an attached flow to a flow with local recirculation region near a corner point of a body contour. It considers both subsonic and supersonic flow regimes, and shows that the flow near a corner can be studied in the framework of the triple-deck theory.

Transitional flow separation upstream of a compression corner

Journal of Spacecraft and Rockets, 1970
Experimental measurements of transitional separation, caused by a compression corner on a two-dimensional model were analyzed in an attempt to correlate the extent of separation. A previously published correlation, based on the wetted length Reynolds number at the separation point, failed when the plate length alone was changed. A re-examination of the

Controlling Corner Stall Separation With Plasma Actuators in a Compressor Cascade

Journal of Turbomachinery, 2015
This paper presents a numerical and experimental assessment of a plasma actuation concept for controlling corner stall separation in a highly loaded compressor cascade. CFD simulations were first carried out to assess actuator effectiveness and determine the best actuation parameters.

Wedge-based corner model for widely separated view matching

Object recognition supported by user interaction for service robots, 2003
A novel interest point detector is presented in this paper. It uses a wedge model that characterizes corners by their orientation and angular width. The detector is compared to two popular corner detectors: Harris and SUSAN. It is also shown how widely separated views can be matched by using information provided by the detector to approximate local ...

Effect of face separation in corner-cube reflectors

Optical Engineering, 2009
We explore the effect of separation between the faces of a corner-cube reflector on its performance. This is important because, in several retroreflector applications, one (or more) face of the module is some type of modulator. The fabrication and assembly of these modules invariably results in, or requires, gaps between the faces.

Corner Separations Around a NACA65 Blade in a Decelerating Flow

Volume 1A: Symposia, Part 2, 2015
In order to examine the fundamental characteristics of a corner separation in a decelerating cascade flow, an experimental apparatus was made and the separations around a NACA65 blade in a decelerating channel flow were examined both experimentally and numerically. The two-dimensional calculations show that the NACA65 cascade flow that has 45 deg.
