Abstract

Local mass transfer coefficients from a horizontal cylinder immersed in a fluidized bed were investigated experimentally. An aluminum cylinder coated with naphthalene, immersed in a fluidized bed of glass beads, was used to obtain mass transfer coefficients. The test results indicated that the local mass transfer was strongly influenced by the angular position and air flow rate. The data obtained show that minimum and maximum Sherwood are found, respectively, at the top and bottom regions of the immersed cylinder.
