Modification of Shear Stress Transport Turbulence Model Using Helicity for Predicting Corner Separation Flow in a Linear Compressor Cascade

, 2020
Three-dimensional corner separation significantly affects compressor performance, but turbulence models struggle to predict it accurately. This paper assesses the capability of the original shear stress transport (SST) turbulence model to predict the ...

Corner separation dynamics in a high-speed compressor cascade based on detached-eddy simulation

, 2020
Corner separation is a vital unsteady flow phenomenon in a compressor and plays an essential role in flow field instability. Moreover, corner separation under high subsonic Mach number conditions is a scientific problem with practical engineering ...

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.

Investigation on the Horn-Like Vortices in Stator Corner Separation Flow in an Axial Flow Pump

, 2020
Stator corner separation flow existing in the guide-vane domain has significant effects on the characteristics of an axial-flow pump. The objective of this paper is to investigate the vortical structures in stator corner separation flow.

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.

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 ...

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.

Control of corner separation via dimpled surface for a highly loaded compressor cascade under different inlet Mach number

Aerospace Science and Technology, 2019
In this paper, flow characteristics of dimpled compressor cascades are numerically discerned by solving the compressible Reynolds-averaged Navier–Stokes equations on structured grids over the inlet Mach number ranging from 0.3 to 0.8.

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
