Influence of Some Parameters on the Bed Expansion

Stands out (Kunii and Levenspiel, 1991; Tannous, 1994):

  • Expansion of a three-dimensional bed is lower than a bidimensional bed for the same gas velocity;
  • Bed expansion is independent of the height of the fixed bed and the column diameter, for large particles, spherical and nonspherical for 10<Remf<270 and 0,14x105<Ar<180x105 .
