Particle motion and particle-convective heat transfer near the walls of fluidized beds. Background: Fluidized bed technology has important industrial applications ranging from petrol production to mineral processing for metal production. Such processes take advantage of the high rates of heat transfer in gas-fluidized beds.\r\nObjective of project: To improve understanding and modelling of heat transfer in gas fluidized beds through the application of state-of-the-art experimental (Positron Emission Particle Tracking) and modelling (Discrete Element Method simulation) techniques. \r\nExpected outcomes of project: New knowledge of the mechanisms of fluidized bed heat transfer. Improved the prediction of heat transfer coefficients with consequent improvements in the design and operation of fluidized bed processes.\r\n\r\n\r\n
