1. Fluidization Reading Materials: Perry’s Handbook, Chapter 17
M. Rhodes, An Introduction to Particle Technology, Chapter 5

7. But why Fluidised bed process?
Good Heat and mass transfer , and easy to control

9. Fluidization

11. Minimum Fluidization Velocity

12. Minimum Fluidization Velocity

14. Slow flow Re < 1

15. Fluidization Velocity

19. Some other correlations

21. 1100
70.4

26. Homogeneous Fluidization
There are two important factors:
Change the porosity
Change the bed height

27. Single settling velocity
= fluidisation velocity not
necessary minimum fluidized
velocity
Single settling velocity

31. Chapter 2

32. Bubbling (two-phase) Fluidization

35. Classification of Powders

42. Motion of bubbles and solids

46. Density of the fluid
Density of the solids

47. Hint: Assume = 0.45 but also validate this assumption
Limiting bubble (or Maximum bubble size)
Hint: Assume = but also validate this assumption

53. Heat Transfer in Fluidized Beds

58. Fluidized Bed Design
