RÉSUMÉ

In a recent paper (Mata, Pereyra, Trallero and Joseph 2002) we computed stability limits for Kelvin-Helmholtz instability of superposed gas-liquid flow, comparing theories of Jeffreys (1925, 1926), Taitel and Dukler (1976), Lin and Hanratty (1986), Barnea and Taitel (1993), and Fimada and Joseph (2001). The theories we compared with literature data on air-water flow and with new data on heavy oil. A problem encountered in the experiments is that the experimental data is presented in a plane of superficial gas and liquid velocities which do not uniquely determine the flow type. A critical view of this method of presenting results is the subject of the remarks to follow...
