Experimental investigation on SPS casing treatment with bias flow
, 2014 Generally, casing treatment (CT) is a passivity method to enhance the stall margin of fan/compressor. A novel casing treatment based on the small disturbance theory and vortex and wave interaction suggestion is a method combining passive control and ...

The Dynamics of the Policy Mix and Sectoral Gaps in South Korea's Decarbonization Transition
Environmental Policy and Governance, EarlyView.ABSTRACT While a coherent policy mix is a fundamental prerequisite for successful energy transitions, existing frameworks predominantly rely on static evaluations. This horizontal approach fails to capture the deep temporal dynamics and physical inertia inherent in socio‐technical regime shifts.

Learning as Compost: Reorienting Evaluation in an Era of Authoritarian Drift
New Directions for Evaluation, EarlyView.ABSTRACT We synthesize insights from seven cases to interrogate a central assumption of the learning function of evaluation: Learning can be strengthened through better design, integration, or alignment with accountability systems. Taking the issue's conceptual framework seriously, the essay reflects what the cases reveal about the nature of learning ...

Study of casing treatment stall margin improvement phenomena
, 1974 The results of a program of experimental and analytical research in casing treatments over axial compressor rotor blade tips are presented. Circumferential groove, axial-skewed slot, and blade angle slot treatments were tested.

Single stage axial compressor stability management with self-recirculating casing treatment
, 2019 A discrete self-recirculating casing treatment (RCT) with converging nozzle and Coanda jet is designed and introduced in a high speed transonic axial compressor stage. Numerical parametric studies for various injection skew/yaw angles are carried out to

Equine Veterinary Journal, EarlyView.Abstract Background FLow‐controlled EXpiration (FLEX) has been shown to significantly enhance oxygenation in horses under clinical and experimental conditions. Objectives To compare pulmonary gas exchange during early recovery following general anaesthesia in horses ventilated with FLEX compared with conventional intermittent positive pressure ...

THE ROLE OF TIP LEAKAGE FLOW IN AXIAL COMPRESSOR SPIKE-TYPE ROTATING STALL INCEPTION
, 2017 The operating range of axial compressors is frequently limited, at low flow rates, by spike-type stall inception. Previous work has identified spikes as radial vortex tubes, created by leading edge separation.
