Resumen:
This paper discusses different issues that appear when characterizing turbulence in two-phase,air-water flows, in relatively deep containers. The flows correspond to bubble plumes withrelatively large bubble diameters. Results of velocity time series obtained with the help ofAcoustic Doppler Velocimeters (ADVs) are presented and analyzed. The post-processing ofthose signals is discussed in detail, presenting a methodology to separate air velocity from watervelocity using ADV. Turbulence statistics, obtained from the time series, are also presented.Specifically, spatial distributions for the turbulent kinetic energy are analyzed. An interpretationof the behavior of the plume in the tank is also provided.
