The subject of the research are the parameters characterising pulsing flow through a TBR bed of a specific class of systems, namely, the systems forming foams of various stability. The investigations have been carried out for the systems in which argon, nitrogen and helium were the gas phases and water solutions of methylene, ethylene and isopropylene alcohols were the liquid phases. The way of determining as well as the results of measurements of the velocity of liquid pulses travelling along the bed have been presented. In the experiments, the physicochemical properties of both phases were varied in order to establish the influence of the gas density as well the viscosity, density and surface tension of the liquid phase on the measured values. It is shown that the real velocity of the gas phase is the most important parameter influencing the pulse velocity. A relationship has been elaborated, which correlates the results of experiments for all the systems investigated with an average relative error 7%.

Przedmiotem badań są parametry charakteryzujące pulsacyjny przepływ przez złoże reaktora typu TBR układów tworzących piany o różnej trwałości. Badania wykonano dla układów, w których fazą gazową były: argon, azot i hel, fazą ciekłą natomiast wodne roztwory alkoholi: metanolu, etanolu, izopropanolu. W niniejszej, pierwszej części opracowania przedstawiono sposób pomiaru oraz wyniki eksperymentów, w których określano prędkość pulsów cieczy wędrujących wzdłuż złoża. W eksperymentach zmieniano właściwości fizykochemiczne obu faz w celu określania wpływu gęstości gazu oraz lepkości, gęstości i napięcia powierzchniowego fazy ciekłej na mierzoną wielkość. Wykazano, że parametrem mającym największy wpływ na prędkość pulsów jest rzeczywista prędkość fazy gazowej. Opracowano zależność, która koreluje wyniki eksperymentów ze średnim błędem względnym nie przekraczającym 7%.
