Turbocharger Structural Integrity [PDF]

open access: yes, 2014
Since the introduction of Euro VI in January 2014, all new diesel powered commercial vehicles have been equipped with turbocharged engines. It is virtually impossible to meet these emission regulations without using a turbocharger.

Discontinuation of Immunotherapy in Patients With Relapsing Myelitis Without AQP4/MOG Antibodies

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT This study assesses the outcomes of immunotherapy discontinuation in patients with relapsing seronegative idiopathic myelitis (SIM), a condition that remains uninvestigated due to its rarity. We reviewed records from 77 patients with relapsing SIM at the National Cancer Center of Korea, focusing on 11 who discontinued treatment after a median ...

Active clearance control system for a turbomachine [PDF]

open access: yes, 1982
An axial compressor is provided with a cooling air manifold surrounding a portion of the shroud, and means for bleeding air from the compressor to the manifold for selectively flowing it in a modulating manner axially along the outer side of the stator ...

Aero-acoustic performance of a continuous transonic wind-tunnel axial-flow compressor

open access: yesXibei Gongye Daxue Xuebao, 2022
A three-stage axial-flow compressor was developed for a continuous transonic wind tunnel. The rotor-stator spacing and the ratio of number of rotor blades to number of stator vanes were properly chosen for the purpose of aero-acoustic noise suppression ...

Stator well flows in axial compressors

open access: yesInternational Journal of Heat and Fluid Flow, 2000
Abstract This paper reports a study of the flow conditions in spaces often found beneath the stationary blades of modern compressors – stator wells. The design of the stator wells in a modern high-pressure turbofan can be a limiting factor. This study shows good comparison with existing experimental data upon the pressures and velocities in related ...

Numerical Simulation of Surge in Axial Compressor [PDF]

open access: yesInternational Journal of Rotating Machinery, 2012
The object of this paper is to provide a reliable tool to simulate the stationary and transient operation performances in multistage axial compression systems, especially poststall behavior. An adapted version of the 1D Euler equations with additional source terms is solved by a time marching and control volume method.

Hydrogel‐Based Capacitive Sensor Model for Ammonium Monitoring in Aquaculture

open access: yesAdvanced Engineering Materials, EarlyView.
Traditional techniques for monitoring aquaculture water quality, particularly ammonium levels, harm fish. This work presents a novel capacitive sensor with an ionic hydrogel transducer to monitor ammonium concentration in real time based on the ammonium‐induced hydrogel dissociation and osmotic pressure. Monitoring aquaculture water quality, especially

Numerical Investigation on Flow Field Distribution of Eccentric Compressors Based on Steady and Unsteady CFD Methods

open access: yesEnergies, 2020
The tip clearance has an important effect on the performance of an engine compressor. While the impact of tip clearance on a concentric compressor has been widely explored in previous research, the flow field distribution of an eccentric compressor has ...
