The article is about schedule of the velocity of the two-phase gas and liquid mixture with simultaneous, up and down flow. These velocities were measured and calculated for three setups of the distribution of the gas phase (multihole, slotted and slottcd filicd with the porous materiał).
This paper presents the comparison of pressure loss of two-phase liquid-gas flow in vertical channel with sudden expansion. 'I'he impact of direction of movement (up-flow or down-flow) have been described.
Currently smaller and smaller channels are used to construct many devices such as mini heat exchangers or mini reactors. Therefore, predicting of two-phase flow pressure drops along minichannels is very important for proper and safely operation of these appliances. Because of this fact, it was decided to carried out introductory research of flow patterns influence on pressure drops in the two-phase flow mixture.
W niniejszym artykule przedstawiono wyniki badań dotyczące wypływu mieszanin dwufazowych ciecz — gaz ze zbiornika przez otwory o nieregularnych kształtach. Uzyskany szeroki zakres danych eksperymentalnych opisano oryginalnymi równaniami korelacyjnymi i przedstawiono w postaci zależności φ = f(Re).

Experimental investigation results of two-phase gas - liquid mixture discharge through irregularly shape orifices from a vessel are presented in the paper. A wide range of experimental data were correlated using original correlation equations and presented in a form of dependence φ = f(Re).
