摘要
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 enhancement
by fluidized solid particles is analyzed with the consideration of collisions of solid particles with the boiling vapor
bubbles.
