Characteristics of Refrigerant Film Thickness, Pressure Drop, and Condensation Heat Transfer in Annular Flow
Results are presented for void fraction, pressure drop, and condensation heat transfer for refrigerants R-11, R-12, R-22, and R-134a over a range of mass fluxes, qualities, and tube sizes. General characteristics and trends in void fraction, pressure drop, and heat transfer for different refrigerants are discussed. Annular flow modeling relations are used to develop ratiometric equations for liquid fraction, pressure drop, and heat transfer that allow general trends to be predicted when the operating parameters of a refrigeration system are changed.
