Abstract

The experiments were performed to clarify the effects of air fluidizing velocity, particle diameter, tube diameter, and pitch between the tubes on the heat-transfer coefficient for a bundle of horizontal tubes immersed in aggregative fluidized bed.
The average heat-transfer coefficient and its maximum value were found to be dependent on the particle diameter, air fluidizing velocity, and the ratios of pitch to tube diameter covered in the present conditions.
The maximum heat-transfer coefficient for the smaller ratios compared with those for the larger ratios was shown to be reduced.
Furthermore, the proposed correlation for the maximum heat-transfer coefficient was found to yield good agreement for both the present results and the ones available from other investigations.
