Summary

A new flow pattern based on data for three different refrigerants covering a wide range of mass velocities, vapour qualities and heat fluxes, is presented, including the prediction of the onset of dryout at the top of the tube during evaporation inside horizontal tubes. The proposed modifications allow an accurate prediction of the flow pattern for very different fluids which are the substitute refrigerants (HFC-134a and HFC-407C) and the natural refrigerant R-717 (ammonia).
