Summary

A NEW METHOD IS PRESENTED FOR THE ANALYSIS OF HYDRODYNAMICS AND HEAT TRANSFER OF TWO-PHASE ANNULAR FLOWS WITH TURBULENT LIQUID FILMS. THE LIQUID FILM IN TWO-PHASE ANNULAR FLOW IS DIVIDED INTO A CONTINUOUS LAYER AND INTO A WAVY LAYER CLOSE TO THE LIQUID-GAS INTERFACE. IN THE CONTINUOUS LIQUID LAYER REGION, IT IS ARGUED THAT THE TURBULENCE STRUCTURE IS THE STRUCTURE OF SINGLE PHASE TURBULENT PIPE FLOW, AND IN THE WAVY LAYER REGION, THAT THE EDDY DIFFUSION LENGTH IS PROPORTIONAL TO THE THICKNESS OF THIS REGION. ANALYTIC RESULTS ARE COMPARED TO THE RESULTS OF OTHER ANALYTICAL MODELS AND TO THE EXPERIMENTAL DATA IN UPFLOW, DOWNFLOW AND HORIZONTAL FLOW. IN ALL CASES CONSIDERED, VERY GOOD COMPARISON IS ACHIEVED IN BOTH HYDRODYNAMICS AND HEAT TRANSFER.
