From Separate Corners to Dialogue and Action
Race and Social Problems, 2009How can higher education programs engage students in building a shared commons to address inequalities and foster commitment to intergroup collaboration? Intergroup dialogue is one such possibility to provide forums for meaningful engagement among students from diverse backgrounds.

Numerical Resolution of Compressor Corner Separation Problem
Volume 2C: Turbomachinery, 2020Abstract Corner separation is a common flow phenomenon within compressors that can significantly affect the compressor performance. The RANS turbulence closures, commonly used in the industrial CFD simulations, often struggle to predict corner separation with reasonable accuracy.

Hypersonic compression corner flow with large separated regions
Journal of Fluid Mechanics, 2019The structure of large-scale hypersonic boundary layer separation and reattachment is studied numerically using a flat plate/compression corner geometry. Apart from verifying the large scale separation characteristics in hypersonic flow, a detailed discussion of secondary separation and fragmentation into multiple vortices embedded within the main ...

On laminar separation at a corner point in transonic flow
Journal of Fluid Mechanics, 2000The separation of the laminar boundary layer from a convex corner on a rigid body contour in transonic flow is studied based on the asymptotic analysis of the Navier–Stokes equations at large values of the Reynolds number. It is shown that the flow in a small vicinity of the separation point is governed, as usual, by strong interaction between the ...

Intermittent corner separation in a linear compressor cascade
Experiments in Fluids, 2013To gain a better knowledge of the mechanisms of corner separation and to obtain a database that could be used to calibrate large eddy simulation, a detailed and accurate experimental investigation of the flow field in a linear compressor cascade has been carried out at a Reynolds number of 3.82 × 105 based on the blade chord and the inlet free stream ...

The Impact of Bleeding on Compressor Stator Corner Separation
ASME-JSME-KSME 2011 Joint Fluids Engineering Conference: Volume 1, Symposia – Parts A, B, C, and D, 2011Bleed air from the high pressure compressor has taken up 3–5% in the air system. However, there are not many studies on the compressor performance after bleeding. By analyzing a low-speed single-stage compressor and a transonic single-stage compressor, this paper presents several plans with different bleeding rates on the casing near stator corner, in ...

On the separation of a supersonic flow at a sharp corner.
AIAA Journal, 1967A qualitative comparison is made between the results of an experimental investigation of the separation of a supersonic flow from the corner of a base and a recently presented solution for the separation of a Stokes-type flow in a similar situation. The form of the flows in the two situations is shown to be remarkably similar and the similarity appears

Shock-Induced Corner Separation in Supersonic Duct Flows
2019The effect of wall separation control on multiple walls was investigated. This study used injection-assisted micro-vortex generators (MVGIs) in a duct flow. Three cases, namely, no control (case A), three-wall control (case B), and four-wall control (case C), were investigated using schlieren imaging, oil flow visualization, and wall pressure ...
