Modelling of transient flow during water hammer considering cavitationin pressure pipes
Języki publikacji
Abstrakty
Przedstawiono dwa modele kawitacji parowej: dyskretny model rozerwania słupa cieczy (CSM) i model kawitacji pęcherzykowej BCM. W obu modelach uwzględniono niestacjonarne opory tarcia w postaci całki splotowej z przyśpieszenia i funkcji wagi. Wyniki obliczeń porównano z dostępnymi z literatury wynikami badań eksperymentalnych. Stwierdzono lepszą ich zgodność niż w przypadku modelu quasi-ustalonych strat tarcia.
The two models of vapour cavitation are presented in the paper: the column separation model (CSM) and bubble cavitation model (BCM). Non-stationary friction resistances have been introduced to both models represented by convolution integral with integrand depending on acceleration and certain weighting function. The results of calculation are compared with published experimental results. A better compatibility has been stated compared with the model of quasi-steady friction loses.
