This study investigates the wall-to-bed heat transfer in three-phase fluidized beds with a cocurrent up-flow of water and air. Various sizes of glass, activated carbon, and alumina beads were fluidized using a brass column heated by a steam jacket. The beads, with diameters ranging from 0.61 to 6.9 mm and densities between 1330 to 3550 kg/m3, were analyzed to evaluate the wall-to-bed heat transfer coefficient based on the axial dispersion model concept. Additionally, complementary experiments were conducted on gas-liquid cocurrent columns and liquid-solid fluidized beds. A correlation was established between the heat transfer coefficients in gas-liquid-solid and liquid-solid configurations, which relates to the ratios of gas to liquid velocities and solid particle properties. Furthermore, an equation for estimating the wall-to-bed heat transfer coefficient in liquid-solid fluidized beds is proposed.
