| Abstract Scope |
C-SiOC coating process on yttria stabilized zirconia (YSZ) microspheres (500 µm) was simulated. The spouted fluidized bed coater configuration was modelled for simulation to understand the fluid and particle dynamics using a Multiphase Flow with Interface Exchange (MFIX) software. Two different coater configurations were studied. Additionally, the influence of Wurster tube configuration at different height intervals from the bottom of the coater set-up was investigated. The effects of process variables such as fluid viscosity, fluid mass in-flow pressure, and geometrical configuration on the particle residence time distribution were also quantified. Instantaneous particle position, particle residence time, and particle velocity distribution inside a fluidized bed coater were evaluated. The effects of geometry and the influence of Ar flow condition at 800C at different mass in-flow pressure were also investigated. The derived results were utilized for coating experiments using a Glatt coater to yield homogeneous and defect-free coatings. |
