A thorough understanding of slurry rheology is required for the design and computational fluid dynamics (CFD) simulation of slurry reactor to obtain optimal performance. A poorly designed reactor will have poor mixing, flow short circuiting and stagnant zones. This project will provide a means of characterising the ammonia phosphate slurry rheology on-line for WMC fertilizer plant, perform detailed rheological characterisation of the slurry with and without trace elements, and provide fluid flow behaviour within the reactor through CFD simulation. A mere 1% improvement over the current solids output of 100tonnes/hr will enhance the revenue by $2.5million/yr for WMC.Read moreRead less

X-ray sources underpin key diagnostic techniques in materials science, advancing applications from structural engineering through to ore processing and energy storage. However, the limited brightness of present-day laboratory x-ray sources restricts the utility and range of these diagnostic techniques. This research intends to use intense lasers to create microscopic plasmas and drive high harmonic generation. The high harmonic generation process is already used to create laser-like ultraviolet light. By optimising the characteristics of the plasma medium, the project aims to extend bright high harmonic generation to the x-ray regime.Read moreRead less
