This project aims to innovate new resistive pipeline backfill materials, associated construction methods and numerical techniques to minimise corrosion at network level, considering interference effects among adjacent pipelines. In contrast to only providing mechanical support, this project will envision backfill for in-line corrosion protection by elucidating its role in pipeline corrosion. The expected outcomes are very effective and low-cost approach and tools to provide in-line protection, in contrast to other protection methods that are expensive and not always possible. The project will bring significant economic benefits by addressing corrosion-induced pipe failures for urban centres, where underground space is heavily congested.

This project aims to develop a particle-scale microprobe to capture the transient dynamics of particle behaviours for pneumatic conveying. Slug flow pneumatic transport of granular materials such as mineral particles and food grains is extremely popular across the processing industry. However, without the fundamental understanding of the conveying mechanism at the particulate level, pneumatic conveyors are over-designed and energy intensive. The project aims to enable accurate measurement of the motion, inertia and force information at the particle scale, so as to produce more accurate design protocols for such a conveying system. Improved pneumatic conveyors may have the potential to reduce the energy consumption in such systems by up to a factor of 10.Read moreRead less

Buried pipeline networks is the most common mode of transporting and distributing water, oil and gas resources and pipeline failures may have a major socioeconomic and environmental impact. The goal is to develop a framework for describing the mechanisms underlying soil-pipe interaction, aiming to reduce the failure risk of pipes affected by geohazards. The project aims to model the response of pipelines in the laboratory, using a new custom-built apparatus. Experimental results are expected to provide insight for developing a theoretical model to quantify the effect of soil moisture on pipe integrity, and propose design formulas. A general framework is intended to be developed for handling various unsaturated soil-structure interaction problems in geotechnical engineering.Read moreRead less
