โฆ Synopsis
Dissolution of irregular particles has been studied in packed beds for the systems of al&aster-water, marble-aqueous HCl solutions and mossy zinc-aqueous acidic I2 solutions, where the sphericity of particles varied in a wide range. The observed values of the Sherwood number have been correlated well by Sh = 2 + 0.31 SC"~ (el" D4p/'/~)~"

Nelson and Galloway's theory of particle to fluid mass transfer in dense systems of fine particles is re-examined and modified slightly to make it applicable to liquid fluidised beds. The resulting expression agrees with published data although these are inadequate to test it critically.
