A fluid catalytic cracking (FCC) unit is an important refinery unit operation responsible for about 45% of total petrol production. The aim of this study is to improve the petrol production efficiency of Australian refineries thus allowing our country not only to maintain its self-sufficiency but also to permit lucrative exports. This will be done by optimising the performance of the FCC unit through novel computational fluid dynamic simulations. The outcomes of this study will enable refiners to produce cleaner fuel (e.g., fuel with less sulphur) and decrease air pollution from the FCC unit (in the form of CO and particulates) thus helping Australia to preserve its diverse and relatively pollution-free environment.Read moreRead less

A novel hydrothermal liquefaction reactor has been developed that has strong potential to overcome the limitations of Muradel's existing demonstration reactor which, while world-leading, is uneconomical at commercial scale. The project aims to develop design tools to optimise the new reactor, comprising a chemical model of the complex, multi-component hydrothermal liquefaction reactions, a computational model of the mixing and heat transfer within it and a network model of the energy and exergy flows.Read moreRead less
Force Interactions in Packed and Fluidised Beds at Micro-Scale Operation. Industrial processing in the 20th century was about increasing size to gain benefit from economies of scale. This century, the focus is on micro devices like lab-on-a-chip and high speed computer processors that deliver their product directly to the consumer. There are significant obstacles facing this new technology.

Industrial processing in the 20th century was about increasing size to gain benefit from economies of scale. This century, the focus is on micro devices like lab-on-a-chip and high speed computer processors that deliver their product directly to the consumer. There are significant obstacles facing this new technology. Mixing is reduced due to laminar flow, and a large amount of energy is needed to move the fluid through such small devices. Particles are often added to improve mixing and heat transfer, but their presence adds to the energy requirements. This study will help us overcome these challenges. Read moreRead less
A coupled finite volume method for viscoelastic flow problems on highly-skewed unstructured meshes: a computational rheology revolution. Commercial tools are unavailable for 21st century industry to analyse complex flow processes involving viscoelastic materials. Using fabrication of microstructured polymer optical fibre as a key case study, a coupled finite volume methodology holds the key for the next generation of computational rheology simulators.
Selective generation of hydrogen from biomass and waste fuels. Biomass fuels account for 14% of global energy supply. This is likely to increase in future as the population increases, energy demand rises, cheap oil and coal reserves are depleted, and the effects of global warming become more readily visible. In Australia the development of a sustainable hydrogen economy is a national priority. The hydrogen economy could bring about improved energy security, substantially reduced greenhouse gas e ....Selective generation of hydrogen from biomass and waste fuels. Biomass fuels account for 14% of global energy supply. This is likely to increase in future as the population increases, energy demand rises, cheap oil and coal reserves are depleted, and the effects of global warming become more readily visible. In Australia the development of a sustainable hydrogen economy is a national priority. The hydrogen economy could bring about improved energy security, substantially reduced greenhouse gas emissions, improved energy efficiency and improved air quality. This proposal directly addresses this challenge by investigating the science underpinning a large-scale sustainable hydrogen synthesis process using biomass and waste fuels. Read moreRead less

Drug delivery systems are an important and growing part of the pharmaceutical and biotechnology market. The growth is estimated to be at 23% p.a. and is tied to the requirements for more precise and complex delivery profiles by highly potent drugs or vaccines (bioactives). To achieve the required level of control and precision, improved encapsulation technologies are needed to produce particles of a precise size and narrow size distribution.
