Efekt przejściowy przy przenikaniu słabej fali uderzeniowej przez rozgałęzienie przewodów

Transmission of a shock wave through a branching of pipes is accompanied by transitional effect including phenomena of plane wave fronts formation and the phenomenon of a corner downstream vortex development. On the basis of visualisational images a quantitative model of transitional effect has been formulated. Calculations of the flow for some values of the incident wave strength (in the range: $1,4<
