Abstract
The study of flow configuration and regime transitions in a vertical pipe is of primary interest for the understanding of the fundamentals of two-phase flow dynamics. Also, it is useful for the calibration of both interfacial forces and population balance models. This simple geometry allows for the isolation of each effect as the dynamics takes place mainly along one dimension. Most investigations deal with the flow configuration for different flow rates of both phases. But further investigations and new interesting results can be obtained by changing the physical properties of the base fluids and analyzing their influence on the flow dynamics. In this work we show the effects of temperature and electrolyte concentration in the flow configuration. The rise of temperature produces an unaccounted acceleration of the transitional effects. The addition of NaCl produces a delay of such effects thanks to the inhibition of bubble coalescence.
