Dynamics of a small gap gas lubricated bearing with Navier slip boundary conditions
A gas lubricated bearing model is derived which is appropriate for a very small bearing face separation by including velocity slip boundary conditions and centrifugal inertia effects. The bearing dynamics is examined when an...

Numerical investigation of laboratory tested cross-flow tidal turbines and Reynolds number scaling
The cross-flow, or vertical axis tidal turbine, is a prominent configuration of marine renewable energy device aimed at converting tidal currents into electrical energy. This paper highlights the hydrodynamic limitations of...
Evaluation of the minimum face clearance of a high-speed gas-lubricated bearing with Navier slip boundary conditions under random excitations
Motivated by ongoing developments in aero-engine technology, a model for a coupled gas-lubricated bearing is developed in terms of an extended dynamical system. A slip boundary condition, characterised by a slip length, is...

How Do Magnetic Field Models Affect Astrophysical Limits on Light Axion-like Particles? An X-Ray Case Study with NGC 1275
Axion-like particles (ALPs) are a well-motivated extension to the standard
model of particle physics, and X-ray observations of cluster-hosted AGN
currently place the most stringent constraints on the ALP coupling...

Abstract: Axion-like particles (ALPs) are a well-motivated extension to the standard model of particle physics, and X-ray observations of cluster-hosted AGN currently place the most stringent constraints on the ALP coupling to...
Infant Mortality and Working-Class Child Care, 1850-1899. By Melanie Reynolds
A Reid
Mar 07, 2017
This book sets out to prove that nineteenth-century working class women were not always bad mothers. For the volume, Reynolds scoured an enormous volume of contemporary reports, newspaper and journal articles, and other sources...
On the dynamics of a high-speed coned fluid-lubricated bearing
An incompressible air-flow model for a fluid film bearing is derived using a modified Reynolds equation for the thin-film dynamics of a rapidly rotating rotor and stator. Mathematical and numerical modelling is applied to the...
Aerodynamics of biplane and tandem wings at low Reynolds numbers
Experiments were performed to investigate the aerodynamic characteristics of two-wing configurations at a low Reynolds number of 100,000. The wing models were rectangular flat plates with a semi-aspect ratio of two. The stagger...
Development and testing of an intervention to increase staff knowledge and confidence in responding to health anxiety in the context of cognitive decline
Background: Memory complaint in the absence of organic pathology is a common phenomenon accounting for up to one third of patients presenting to memory clinics. Health anxiety has been specifically linked to dementia worry and...

ERT as Mobile Learning by Necessity
The term as below Emergency Remote Teaching (ERT) has been adopted worldwide. In practice, approaches to ERT have been contextual with diverse lecturer and student experiences owing to complex assemblages of sociomaterial...

Unsteady Lift and Moment of a Periodically Plunging Airfoil
To simulate the effects of gusts and maneuvers, lift, moment, and flow measurements are presented for a periodically plunging airfoil at a Reynolds number of 20,000 over a wide range of reduced frequency (k≤1.1), amplitude...
Numerical modelling of unsteady turbulent flow in tubes, including the effects of roughness and large changes in Reynolds number
David Nigel Johnston
Aug 01, 2011
A method has been developed for predicting unsteady turbulent friction in smooth, transitional and rough pipe flow. For transitional and rough pipe flow the effective viscosity at the wall is varied depending on Reynolds number...
Rotationally induced ingress in rotor–stator systems
The presence of a rotating disk adjacent to a stationary disk forms a rotor–stator cavity known as a wheel-space. It is necessary for gas turbine wheel-spaces to be purged with sealing flow bled from the compressor to counteract...
Considerations for Setting Up Play Therapy Training Clinics
When setting up a play therapy training clinic, there are many considerations to explore regarding designing a therapeutic space, selecting toys and other materials, exploring the rationale for the toy selection and examining...

Lift enhancement by means of small-amplitude airfoil oscillations at low Reynolds numbers
Force and particle image velocimetry measurements were conducted on a NACA 0012 airfoil undergoing small-amplitude sinusoidal plunge oscillations at a poststall angle of attack and Reynolds number of 10,000. With increasing...
Effect of random forcing on fluid-lubricated bearing
A model for a fluid-lubricated bearing is derived for operation under conditions where external forces are subject to random fluctuations that may act to destabilize the bearing. The fluid flow through the bearing is described...
