| Abstract: | Theoretical analyses and experimental studies on flow boiling heat transfer were made in a vapor-liquid-solid three-phase fluidized bed. A heat transfer coefficient correlation incorporating asymptotic model and suface renewal was proposed. In this heat transfer coefficient correlation,total heat transfer between the fluidized bed and wall surface is divided into three parts:convection heat transfer between solid particles and wall surface, convection heat transfer between vapor-liquid two-phase flow and wall and flow nuclei boiling heat transfer with the presence of solid particles. The calculated values agree well with the experimental data. |

| Keywords: | three-phase flow flow boiling circulating fluidized bed |
