Interpolation formulas are derived to determine the active particle fluidized bed heat and mass transfer coefficients. The formulas agree fairly well with experimental data in a wide range of Archimedes numbers 102 < Ar < 10 and reflect the existence of non-coinciding limiting Nusselt and Sherwood numbers as Re -ì 0 , as well as the difference in gas flow regimes around an isolated sphere and an active particle immersed in a fluidized bed.
