The paper describes results of experimental investigations of condensation of the refrigerant R404A in the flow through a coiled tube under conditions of external disturbances that occur in refrigeration units. The development and decay of condensation is induced by impulse changes of parameters of the two-phase system, such as pressure and mass flux density in the tubular channel. It is confirmed...
W opracowaniu ograniczono zakres analizy do dwóch charakterystycznych przemian fazowych, to znaczy wrzenia i skraplania. Bez względu na to, czy przemiana fazowa zachodzi w objętości, czy też w przepływie, występowanie stanów niestabilnych tłumaczy się powstawaniem warunków nierównowagi termodynamicznej podczas ich realizacji. Wspólna przyczyna wywołania niestabilności skutkuje bardzo wieloma ich odmianami...
