Considerable efforts are being made to minimise the environmental impacts of fossil fuels by utilising renewable energy sources like biomass. Many of the challenges associated with the thermal conversion of biomass relate to its char characteristics. The aim of this project is to gain a fundamental understanding about the impact of reaction conditions during the pyrolytic stage on the structural and compositional transformations of the resultant char, its combustion and gasification reactivities, and the release of inorganic matter and ash formation. This holistic and integrated approach should reveal the underlying science necessary to support existing and future biomass use.Read moreRead less
Combined Particle Image Velocimetry (PIV) and CFD modelling to study particle deposition in conduits. System geometry greatly influences flow hydrodynamics and hence the transport of colloidal particles and ionic species from the bulk to the surfaces that result in formation of unwanted deposit matter on the surface. The formation of unwanted deposits has significant environmental and economic penalties. This project uses a new approach that is combining the CFD modelling and experimentation inc ....Combined Particle Image Velocimetry (PIV) and CFD modelling to study particle deposition in conduits. System geometry greatly influences flow hydrodynamics and hence the transport of colloidal particles and ionic species from the bulk to the surfaces that result in formation of unwanted deposit matter on the surface. The formation of unwanted deposits has significant environmental and economic penalties. This project uses a new approach that is combining the CFD modelling and experimentation including flow visualization by PIV to systematically investigate the effect of channel geometry and flow on deposit formation. The outcomes of the project will result in a better understanding and formulating of the effect of geometry on deposition of colloidal particles and ionic species on the surfaces. The results contribute not only towards the mitigation processes for unwanted deposition; it also advances the knowledge in coating applications.Read moreRead less
