Biography

Dr. Craig Meskell is an Associate Professor in the Department of Mechanical and Manufacturing Engineering in Trinity College, Dublin. His primary degree is in Aeronautical Engineering from QUB. He earned his PhD for work on flow-induced vibration in heat exchanger tube bundles. He has also been a Visiting Professor at McMaster University. His technical expertise is in the area of unsteady fluid mechanics, especially when coupled with noise, vibration or structural interaction. For nearly a decade, he has focussed his work almost exclusively on power generating and energy conversion applications, having been active in the field of aircraft noise at a European level. His favourite colour is red Recent and ongoing projects include: flow-induced vibration in nuclear steam generators; flow-induced noise in gas heat exchangers; system identification for wave energy conversion devices; modelling of flow-induced vibration in large, commercial scale wind turbines; and energy efficiency through optimized compressed air use in industrial scale manufacturing sites. Support for his work on energy devices has come from SFI, IRCSET, EI, HEA.

Project Title

Modelling acoustic resonance in heat exchangers

From

Oct 2010

Sept 2014

Summary

Heat exchangers can exhibit periodic vortex shedding. If the fluid is gas flow, then the vortex shedding may excite an acoustic duct mode and hence cause acoustic resonance. The acoustic sources are distributed and diffuse. The onset, and lock-in behaviour depends on the non-linear interaction between the (linear) acoustic field and the fluid dynamics. This project uses unsteady CFD to investigate the spatial and temporal distribution of acoustic sources.

Project Title

System Identification for a wave energy conversion devices

From

Oct 2010

Sept 2014

Summary

The dynamics a self reacting wave energy converter, especially as it exhibits parametric roll/pitch, are modelled using a non-linear panel method. The response obtained is used to identify a simplified 7 degree of freedom lumped parameter model.

Project Title

Flow-induced vibration of nuclear steam generators

From

Oct 2011

Sept 2015

Summary

Nuclear power plant depends on large heat exchangers, called steam generators, to transfer the heat from the reactor to steam, so that electricity can be generated at the turbines. These steam generators are effective bundles of long, thin (and hence flexible) tubes subject to flow perpendicular to their axes. This gives rise to the possibility of flow-induced vibration. In this project we are investigating a recently discovered phenomenon in tube arrays, called bi-stable flow. We are focussing on a tube bundle arrange in a parallel triangular array pattern with a pitch ratio of 1.375 as this is typical of what is used in CANDU reactors.

Project Title

Investigation of flow-induced vibration of horizontal axis wind turbines

From

Oct 2010

Sept 2014

Summary

Industrial scale wind turbines must be able to withstand occasional extreme winds. This includes gusts which cause a rapid change in wind direction. This will mean that the blades are now are very high, even reflexive, angles of incidence to the flow, and so may be considered as bluff bodies, rather than streamlined lifting surfaces. In this project, we investigate the possibility of wind turbine blade sections experiencing vortex shedding, and vortex shedding lock-in due to structural motion, at high angles of attack. The simulated data is used to obtain a simple non-linear wake model which is coupled to the motion of the structure.
