То calculation of autovibrations, initiated by spontaneous flow condensation in transonic region of laval nozzle

The work is devoted to adaptation of explicit MacCormack's scheme to the problem of numerical simulation of autovibrations, excited by overcritical latent heat of vaporization emission. The comparision of numerical results with Barchdorff's experimental data for the steam testifies good reproduction accuracy of stationary condensation shocks and frequency and amplitude of autovibrations in the frame of formulated computational algorithm. The influence of scale and shape of canal on autovibrations and validity of similarity laws received in onedimentional approarch are examined.
