Understanding and Controlling Wall Deposition in Spray Dryers via Experimental and Computational Fluid Dynamics (CFD) Studies. A key problem in operating spray dryers for producing milk powders and other consumer products, such as detergents, is the occurrence of internal wall deposits of powder, leading to thermal degradation of the products and potential fire hazards. However, no fundamental theory has been applied in spray dryers to allow this process to be controlled. The proposed project wi ....Understanding and Controlling Wall Deposition in Spray Dryers via Experimental and Computational Fluid Dynamics (CFD) Studies. A key problem in operating spray dryers for producing milk powders and other consumer products, such as detergents, is the occurrence of internal wall deposits of powder, leading to thermal degradation of the products and potential fire hazards. However, no fundamental theory has been applied in spray dryers to allow this process to be controlled. The proposed project will use state-of-the-art experimental and computational techniques to gain a fundamental understanding of this phenomenon and will develop a validated wall deposition model to predict when and to what extent this process occurs, to give higher throughputs and/or more efficient systems.Read moreRead less

Fine Structured Optical Fibre Fabrication - Soot, Rheology and Nanostructure in Modified Chemical Vapour Deposition. For 30 years photonics and telecommunications have relied heavily on optical fibres made by Modified Chemical Vapour Deposition (MCVD), a complex, highly dynamic process with many interacting variables, which is still more art than science. The results are good enough for most purposes but the next generation of photonics demands fibres with intricate, precisely defined internal s ....Fine Structured Optical Fibre Fabrication - Soot, Rheology and Nanostructure in Modified Chemical Vapour Deposition. For 30 years photonics and telecommunications have relied heavily on optical fibres made by Modified Chemical Vapour Deposition (MCVD), a complex, highly dynamic process with many interacting variables, which is still more art than science. The results are good enough for most purposes but the next generation of photonics demands fibres with intricate, precisely defined internal structures. A multi-disciplinary team will elucidate and quantify the exact nature of the fundamental science underlying MCVD - of silicate soot formation, deposition and heat treatment - and translate this into reproducibly fabricated fine structured fibres with high optical and mechanical performance.Read moreRead less

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
