A new method was developed for measuring the local heat transfer coefficients of a horizontal tube immersed in an aerated vibrating fluidized bed. The local heat transfer characteristics of the horizontal tube was investigated experimentally. The test results indicate that local heat transfer coefficients are influenced by angular position and gas flow rate

as well as vibration frequency and amplitude. When being aerated

the optimum vibration acceleration corresponding to the best effects of heat transfer is less than non-aerated. With vibration

the optimum gas flow rate is less than without vibration. Vibration frequency and amplitude have roughly the same effect on local heat transfer coefficients. In addition

the local heat transfer coefficients exhibited a general tendency to increase with decreasing particle size.
