Numerical Investigation of Gas-Solid Fluidized Beds: Model Development, Validation, and Application

Gas-solid fluidized beds are employed in numerous industrial applications, but the flow dynamics are not yet understood comprehensively. The focus of this dissertation is set on investigating these internal phenomena via Computational Fluid Dynamics (CFD). Numerical models are developed and validated, which allow an accurate prediction of the gas-solid flow fields in various fluidized bed applications, as well as their coupling to mixing efficiency, heat transfer, and material conversion.
