摘要: A continuum bubbly mixture model coupled to the Rayleigh-Plesset equation for bubble dynamics is employed study one-dimensional steady cavitating flows through a converging-diverging nozzle. distribution of nuclei sizes specified upstream nozzle, and cavitation number nozzle contraction are chosen so that occurs in flow. The computational results show very strong interactions between bubbles size may have significant effects on flow; it shown reduces level fluctuations therefore loss compared monodisperse distribution. Another interesting interaction effect flashing instability as flow reaches critical state downstream stability analysis proposed predict variables
