| Description
| - The cavitating flow behaviour is very sensitive to nuclei content, which is undoubtedly dependent on the physical properties of the liquid. For water, it is believed that heterogenous nucleation initiators prevail over homogeneous nucleation and this is understood to be the reason why the classical nucleation theories are regarded as unreliable for the treatment of cavitation. As a result, the problem of nuclei content is typically treated either empirically or experimentally. In this paper we show how the empirical approach can be used to obtain a useful picture of the cavitation flow aggressiveness (erosion potential) using numerical modelling of the turbulent cavitating flow. In addition, we present the latest advances in the understanding of the bubble nucleation process under cavitating conditions based on the modified binary nucleation theory.

- Chování kavitujcího proudu kapaliny je velmi citlivé na množství nukleačních jader, jež závisí na fyzikálních vlastnostech kapaliny. V případě vody se předpokládá, že kavitace způsobená heterogenní nukleací převažuje nad nukleací homogenní. A proto je v současné době klasická teorie nukleace považována za nepříliš spolehlivou pro předpovědi kavitačních dějů. Problém určení množství nukleačních jader v kapalině je pak řešen buď empiricky nebo experimentálně. V této práci uvádíme numerický model kavitujícího turbulentního proudění, jež využívá empirický odhad nukleace k získání představy o erozních účincích kavitujícího proudění. Navíc prezentujeme výsledky modifikované klasické nukleační teorie, která dává uspokojivé předpovědi nukleace při kavitaci ve vodě s rozpuštěným plynem. (cs)
