Heat transfer characteristics was investigated in liquid-fluidized beds using particle mixtures, which mix homogeneously during fluidization in fluidizing columns. In the experiment, fluidization columns having a diameter of 21, 36 and 56 mm were provided, and water was used as a fluidizing liquid. Tested particles were of glass and ceramics, and their diameter range was from 1.87 mm to 6.98 mm. It was found, that the heat transfer coefficient for particle mixtures can be predicted by an appropriate correlation for single-kind particles, when the mean particle diameter and density are evaluated from volume fraction and from mass fraction, respectively.
