The paper presented a short literature review of theoretical models of formation of gas bubbles. On this basis, was prepare a classification of model. In the next step, experimental research was conducted, on the basis of which three were selected basic structure of the formation of bubbles. On the next step Then presents the results of experimental studies on the basis of which three were selected basic structure of the formation of bubbles. The classifications of bubble formation structures were expressed by Eötvös and Reynolds numbers. Furthermore, on this basis, were constructed a map of the structures forming bubbles. This paper presents a measurement method used for determination of parameters of bubbles forming at jet attachment from which the bubbles are displaced upward.

Praca zawiera krótki przegląd literaturowy modeli teoretycznych tworzenia się pęcherzyków gazu. Na tej podstawie przeprowadzono klasyfikację modeli. Następnie przedstawiono wyniki badań eksperymentalnych, na podstawie których wyłoniono trzy podstawowe struktury tworzenia się pęcherzyków. Klasyfikacje struktur oparto na liczbach kryterialnych Reynoldsa oraz Eötvösa. Posłużyło to do opracowania map struktur tworzenia się pęcherzyków. Ponadto w pracy przedstawiono metodę pomiarową do wyznaczania objętości tworzących się pęcherzyków gazu.
