Experimental investigation on stall characteristics of contra-rotating compressor with variable speed ratios

open access: yesXibei Gongye Daxue Xuebao, 2021
By experiment at a low-speed large-scale axial contra-rotating compressor, the near stall points of 19 speed configurations were captured and the stall characteristics under different speed ratios were obtained successfully.

Method of Improving Stability of a Highly-Loaded Axial Compressor Stage by Coupling Different Casing Treatments [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2022
Casing treatment is a powerful method for improving the stability of aircraft compressors. An optimized slot-type casing treatment was tested on the first rotor of a highly-loaded two-stage compressor, and the results showed that the casing treatment ...

RANS CFD Analysis of Hump Formation Mechanism in Double-Suction Centrifugal Pump under Part Load Condition

open access: yesEnergies, 2021
The RANS (Reynolds-averaged Navier–Stokes equations) with CFD (Computational Fluid Dynamics) simulation method is used to analyze the head hump formation mechanism in the double-suction centrifugal pump under a part load condition.

Delaying the Stall of A Low-Wing Aircraft Using A Novel Powerful Vortex Generator

open access: yesInventions, 2022
In this study, a new aerodynamic surface concept is introduced, which is a powerful vortex generator (PVG). It can delay the stall point in a low-wing aircraft. This delay leads to a significant increase in the CLmax of an aircraft.

Boundary Layer Separation and Reattachment Detection on Airfoils by Thermal Flow Sensors

open access: yesSensors, 2012
A sensor concept for detection of boundary layer separation (flow separation, stall) and reattachment on airfoils is introduced in this paper. Boundary layer separation and reattachment are phenomena of fluid mechanics showing characteristics of ...
