PIGNAT Combined Fluidization – FLM2000



Liquid-solid and gas-solid fluidization study

Theoretical and experimental study of fluidization

  • Porosity and expansion of bed, bubbling
  • Theoretically determination of the minimum fluidization velocity: Kozeny-Carman and Ergun equation
  • Experimentally determine the minimum fluidization speed

Study the influence of parameters on fluidization

  • Bed characteristics:
    • Particle diameter and density
    • Bed porosity and height.
  • Fluid characteristics:
    • Fluid flow rate and nature
