Abstract

Local measurements have been carried out in a mercury-nitrogen two-phase flow using the hot-film anemometric technique, in a cylindrical pipe with electrically insulated walls. The flow was turbulent (Re = 63000) and in the bubbly regime (〈α〉 ≈ 0.03). The maximum intensity of the magnetic field was 0.94 T. Processing of the hot-film signal provided in this medium, for the first time, simultaneous quantitative data for the local time-averaged velocity of the liquid-phase turbulent fluctuations, as well as local void fractions. These data were checked against those obtained, for the same conditions, using a double conductivity probe. The latter also provided information on the bubble velocity and average bubble size. Turbulence spectra were also measured.
