Summary: Jingyuan Sun has been awarded the 2014 Newton International Fellowships with collaboration of Professor Yong Yan in the University of Kent, Canterbury. The research subject is ‘Characterisation of fluidisation processes through advanced monitoring and computational modelling’.
Gas-solid fluidised bed reactors are widely used in various industrial processes, particularly in the chemical engineering, energy and food industries. However, the intense motion of particles and gas and the flow structures (bubbles, vortices, particle clusters) in the reactors easily results in hot spots, particle agglomeration, fouling, stagnant zone and particle segregation, which can lead to system shutdown and possible economic losses. It is imperative to elucidate the particle and gas hydrodynamics to prevent and solve such problems. The fluidisation process, when fitted with suitable sensors, generates useful signals, which contain abundant information about the hydrodynamics. Experimental measurement is a practical approach, but to date it still cannot provide a comprehensive description of the fluidisation process due to the natural complexity of the hydrodynamics. Computational fluid dynamics (CFD) modelling is a powerful tool to study complex multiphase flow phenomena such as the fluidisation process. Additionally, advanced signal processing algorithms should be incorporated to extract and fuse the information from the signals. This project is proposed to characterise the hydrodynamics through multimodal sensor integration, multi-scale data fusion, advanced signal processing and CFD modelling.
The research field of Dr. Sun includes chemical engineering, fluidisation process, multiphase flow measurement, computational fluid dynamics (CFD) simulation and gas-solid flow hydrodynamics.
