摘　　要：Experimental study was carried out of liquid flow boiling heat transfer with fluidizedsolid particles in a vertical annulus. Water and aqueous solutions of carboxy methyl cellulosewere used as the working fluids. Solid particles were glass beads of different diameter. Theexperimental results showed that the liquid flow boiling heat transfer was much increasedand the superheat of liquid at heating surface was lowered remarkably by the introductionof the fluidized solid particles. Experimental data were correlated and an empirical equationfor the heat transfer of the three phase flow boiling was obtained.Experimental study was carried out of liquid flow boiling heat transfer with fluidizedsolid particles in a vertical annulus.
