💨 Fluidization Dynamics (Minimum Fluidization Velocity Umf m/s, Ergun Equation, Bed Expansion)

Fluid Bed Minimum Fluidization (Umf) Calculator

Calculate minimum fluidization superficial air velocity ($U_{mf} ext{ in m/s}$) and bed expansion ratio for pharmaceutical and chemical fluid bed dryers (Glatt / GEA Niro / Freund-Vector) using the Ergun equation: determine particle Geldart classification (Group A, B, C, D), prevent channeling and defluidization, and process equipment yields.
