Ultrasonic quantitative imaging with limited view arrays
, Pages: 714-721, ISSN: 0094-243XQuantitative imaging has potential to improve the reliability of damage detection over traditional reflection imaging. However, it is particularly prone to severe artefacts when only a limited aperture is used to measure data. We have introduced VISCIT, the virtual image space component iterative technique, to address this, providing significantly more accurate velocity map reconstructions from both numerical and experimental data.

Monitoring of corrosion in pipelines using guided waves and permanently installed transducers.
, J Acoust Soc Am, Vol: 132Guided Wave Testing (GWT) of pipelines for the detection of corrosion has been developed over about 20 years and is now a well established method worldwide, used mostly in the oil and gas industry. The established approach is as a screening tool: GWT is used to detect the presence of significant reflectors which are then examined locally in detail using conventional methods of NDE. To date most of the equipment has been developed for deployment solely at the time of test. However recent developments include permanently-attached transducers which can be left in place after testing, for example to allow easier access for future testing at difficult locations such as buried pipes. This is enabling a new approach, in which improved sensitivity may be achieved by detecting changes with respect to earlier reference signals, and also continuous monitoring which may follow degradation during service. The presentation will include a summary of the GWT method and discussion of current research for monitoring.

Collective bubble dynamics near a surface in a weak acoustic standing wave field
, JOURNAL OF THE ACOUSTICAL SOCIETY OF AMERICA, Vol: 132, Pages: {37-47}-{37-47}, ISSN: 0001-4966The transport of bubbles to a neighboring surface is very important in surface chemistry, bioengineering, and ultrasonic cleaning, etc. This paper proposes a multi-bubble transport method by using an acoustic standing wave field and establishes a model that explains the multi-bubble translation by expressing the balance between Bjerknes forces and hydrodynamic forces on a bubble in a liquid medium. Results indicated that the influence of primary Bjerknes force, secondary Bjerknes force, and buoyancy force on the bubble translation depends on the position of the target bubble in the acoustic field. Moreover, it was found that increasing the size of a bubble or pressure amplitude can accelerate the bubble motion and enhance the bubble-bubble interaction. The secondary Bjerknes force between two bubbles can switch from an attractive one when they oscillate in phase to a repulsive one when the bubble oscillations are out of phase. These findings provide an insight into the multi-bubble translation near a surface and can be applied to future bubble motion control studies, especially in drug delivery, sonoporation, and ultrasonic cleaning.
