Heat transfer characteristics are studied for gas carrying evaporation with
fluidized solid particles in a vertical rectangular conduit. Experimental
results show that heat transfer of gas carrying evaporation is enhanced and
the superheat of liquid in contact with heating surface lowers remarkably
by introducing solid particles. Nucleate boiling on the heating surface is
suppressed to a considerable degree. The mechanism of heat transfer enhance
ment by fluidized solid particles is analyzed with the consideration of col
lisions of solid particles with the boiling vapor bubbles.
