TL;DR: In this article, an anemometer survey of the 3D flow field in NASA rotor 67, a low aspect ratio transonic axial-flow fan rotor, was performed at design speed at near peak efficiency and near stall operating conditions.

TL;DR: In this article, a transonic single-stage axial compressor using active feedback control was used to stabilize the first and second spatial harmonics of the prestall perturbations using constant gain feedback.

TL;DR: In this article, a transonic single-stage axial compressor using active feedback control was used to stabilize the first and second spatial harmonics of the prestall perturbations using constant gain feedback.

TL;DR: In this article, a transonic axial compressor rotor with dis-crete injection is examined in a time-averaged Navier-Stokes CFD simulations and it is shown that tip injection increases stability by unloading the rotor tip and that increasing injection velocity improves the effectiveness of tip injection.

TL;DR: In this paper, the authors compare measured tip clearance flow details (e.g., trajectory and radial extent) with corresponding data obtained from a numerical simulation and make recommendations for achieving accurate numerical simulation of tip clearance flows.
