Comparison of metrics for the evaluation of similarity in acoustic pressure signals
MESKELL, CRAIG (2013)Determining if aeroacoustic sound predictions are accurate is di cult because the question of how to de ne `accurate' remains open. This communication evaluates four metrics for comparing time-domain pressure signals, ... -
A Decrement Method for Quantifying Nonlinear and Linear Damping in Multidegree of Freedom Systems
MESKELL, CRAIG (2011)A method is presented which can estimate the linear and nonlinear damping parameters in a lightly damped multidegree of freedom system which allows the system to be decomposed into a set of single degree of freedom nonlinear ... -
Evaluation of high frequency vibrations using electronic speckle pattern interferometry
MESKELL, CRAIG (2002)The available techniques for the study of high frequency vibration using electronic speckle pattern interferometry (ESPI) are briefly surveyed. We concentrate on two methods in particular. The first is a straightforward ... -
Fast numerical simulation of vortex shedding in tube arrays using a discrete vortex method
MESKELL, CRAIG; Sweeney, Conor (2003)Vortex shedding may occur in tube arrays, resulting in strong excitation forces at discrete frequencies. In the past the Strouhal numbers governing vortex shedding in these systems were determined primarily by experiment. ... -
Investigation on parametrically excited motions of point absorbers in regular waves.
MESKELL, CRAIG (2016)Free floating objects such as a self - reacting wave energy converter (WEC), may experience a condition known as parametric resonance. In this situation, at least two degrees of freedom become coupl ed when the ... -
Microphone Arrays as a Leakage Detection Tool in Industrial Compressed Air Systems
MESKELL, CRAIG (2012)Compressed air energy is expensive, but common in industrial manufacturing plant. However, a significant part of the generated compressed air energy is lost due to leakage. Best practice requires ongoing leak detection and ... -
A new model for damping controlled fluidelastic instability in heat exchanger tube arrays
MESKELL, CRAIG (2009)Heat exchnager tube arrays are susceptible to damage due to flow-induced vibration, with fluidelastic instability the potnetially the most destructive mechanism. In this paper a simple wake model consisting of a convecting ... -
A practical approach to parameter identification for a lightly damped, weakly nonlinear system
MESKELL, CRAIG; Eret, Petr (Elsevier, 2008)Fluidelastic systems are often lightly damped and exhibit weak non-linear damping. The weak linear and non-linear damping forces have a significant effect on the long term behaviour of the system. However, parameter ... -
Vortex shedding from a wind turbine blade section at high angles of attack
MESKELL, CRAIG (2013)The unsteady flow around a stationary two-dimensional wind turbine blade section (NREL S809) has been simulated using unsteady RANS with the SST turbulence model at Re = 106 and high angles of attack. Vortex shedding ...
