Next generation nondestructive inspection using guided-wave mixing. This project aims to develop a novel approach for early damage detection. It relies on a systematic experimental investigation of nonlinear ultrasonic interaction between different input wave modes in the presence of damage, so as to identify optimal mode selections and operating parameters that will maximise the sensitivity to particular forms of structural damage.

This project aims to develop a novel approach for early damage detection. It relies on a systematic experimental investigation of nonlinear ultrasonic interaction between different input wave modes in the presence of damage, so as to identify optimal mode selections and operating parameters that will maximise the sensitivity to particular forms of structural damage. The effects of in-service loading on wave-mixing response, and non-contact detection suitable for hard-to-inspect surface conditions, will also be investigated. The new developments will help transform existing schedule-based maintenance practice to a condition-based maintenance paradigm, to achieve significant cost savings in maintenance.Read moreRead less
Thermal transport in multi-phase flows for concentrating solar applications. This project seeks to advance the field of heat transfer in high-temperature systems involving liquid metals, with emphasis on energy storage and solar power technologies. The concept couples a tubular sodium boiler with a sodium chloride phase-change storage system for continuous energy supply. Sodium chloride is low cost and has a melting temperature suitable for a wide range of industrial processes. The project plans ....Thermal transport in multi-phase flows for concentrating solar applications. This project seeks to advance the field of heat transfer in high-temperature systems involving liquid metals, with emphasis on energy storage and solar power technologies. The concept couples a tubular sodium boiler with a sodium chloride phase-change storage system for continuous energy supply. Sodium chloride is low cost and has a melting temperature suitable for a wide range of industrial processes. The project plans to address the challenge of sodium stability in highly irradiated tubes by investigating mass, momentum, energy and radiative transport in liquid metals. It is intended that this will inform the design and testing of novel sodium boilers to provide stable and isothermal process heat for continuous or on-demand production of power, chemical fuels and commodities.Read moreRead less
