Hydrodynamics of gas-solid fluidization of a homogeneous ternary mixture in a conical bed: Prediction of bed expansion and bed fluctuation ratios

- Hydrodynamic characteristics of ternary mixture in conical fluidized bed were studied.
- Dimensional analysis and factorial design were used to investigate influence of process parameters.
- Correlations for determining fluctuation and expansion ratios were derived.
- Predicted values using the correlations were in good agreement with experimental data.
