Wet Particulate Materials - Flow or Fracture? Most advanced materials are produced from starting materials in the form of fine particles. Powders, especially in ceramic engineering, are first processed wet into near-final shape. Improved understanding of the fracture of particle networks is critical in order to process nano-sized advanced ceramic materials for use in solar energy harvesting and extreme heat engine applications as well as minimising drying cracks in paints and coatings. The resea ....Wet Particulate Materials - Flow or Fracture? Most advanced materials are produced from starting materials in the form of fine particles. Powders, especially in ceramic engineering, are first processed wet into near-final shape. Improved understanding of the fracture of particle networks is critical in order to process nano-sized advanced ceramic materials for use in solar energy harvesting and extreme heat engine applications as well as minimising drying cracks in paints and coatings. The research aims to identify the fundamental link between particle network strength and structure and the fracture of wet powder bodies. The microscopic mechanisms that control the behaviour will be investigated with a particular focus on toughening mechanisms including the influence of plasticity.Read moreRead less
Novel and cost effective mixing technique for anaerobic digesters in municipal wastewater treatment plants. The mixing system and the models that will be developed in this project will be useful in improving the energy efficiency of anaerobic digesters operated in many towns and cities. These improvements will help to reduce greenhouse emissions significantly and also lead to reduced household water bills, as wastewater treatment costs will decrease.
Reducing land and infrastructure requirements for water evaporation from biosludge through dry stacking. Melbourne's wastewater treatment plants have limited capacity in their evaporation pans to dry residual solids from wastewater treatment processes. This project will significantly improve the efficiency of new pans by providing an alternative operating method, dry stacking, which has delivered considerable benefits to the mineral industry.
Biosolid flow, separation and activity in anaerobic lagoons. This project aims to develop a fundamental model of the complex, non-steady state flow behaviour in anaerobic lagoons. The project will develop new operating procedures and designs for large municipal, industrial and agricultural anaerobic lagoons. This will improve the efficiency of anaerobic digestion and reduce wastewater treatment costs, as well as increase renewable and sustainable biogas production. The intended outcome is a va ....Biosolid flow, separation and activity in anaerobic lagoons.

The project will develop new operating procedures and designs for large municipal, industrial and agricultural anaerobic lagoons. This will improve the efficiency of anaerobic digestion and reduce wastewater treatment costs, as well as increase renewable and sustainable biogas production. The intended outcome is a validated 3D model that captures the physical and biological complexities of anaerobic lagoons. This will impact the design and operation of partner organisation lagoons, reducing capital and operating costs and improving biogas production.Read moreRead less

This project aims to develop a foundation for understanding how microscopic topology and intermolecular interactions control the flow behaviour of supramolecular polymer networks. Brownian dynamics algorithms will be developed to unravel the complex dynamics of the network and calibrated by comparison with carefully designed experiments. The expected outcome of the project is a quantitative framework for connecting the molecular structure and energy landscape with resulting macroscopic properties. This project should yield significant benefit in the rational design of supramolecular systems in which the thermorheological properties can be tuned over a wide range of force/time scales with applications spanning from enhanced oil recovery to injectable hydrogels.Read moreRead less
Designing polymer additives to control breakup of jets and impacting drops. Current agricultural spraying of pesticides is inefficient, causing serious environmental contamination. The project aims to design polymeric additives to control the fluid dynamics of spraying so that drops reach, and then adhere to their target leaf surfaces.
