ABSTRACT:
Heat transfer coefficients were measured in 0.29 m ID and 1.56 m ID fluidization
columns with the same heater tube, identical alumina particles and geometrically scaled
distributors. The maximum coefficients occurred in the turbulent fluidization flow regime.
The Froude number based on superficial velocity and column diameter captures the
scale-up effect well, so long as the heater is located in a region of similar flow structure.
