An experimental study on the heat transfer characteristics between gas and solid phase in a centrifugal fluidized bed was performed.Glass bead

sand and alumina bead were used as bed material in the heat transfer test.The gas temperatures at the inlet and outlet and the bed temperature were measured with thermocouples.The influences of bed thickness

particle diameter

the characteristics of bed material

the rotating speed of the bed and gas superficial velocity on the heat transfer between gas and Particles were examined.An empirical correlation which can be used to calculate the gas-solid heat transfer coefficient in the centrifugal fluidized bed was obtained.
