The experiment was performed on a model Francis turbine in which pressure pulsations on the draft-tube wall and the cavitation-vortex dynamics were acquired simultaneously. The cavitation-vortex dynamics was recorded using a visualization method. An experimental model was proposed in which the cavitation-vortex dynamics was predicted based on recorded pressure information at one point on the draft-tube wall. The performance of the model is, on average, very good. The prediction of the cavitation-vortex dynamics shows better results when the distance between the pressure sensor and the cavitation vortex is short"},{"@xml:lang":"sl","#text":"V prispevku je predstavljen vpliv tlačnih utripanj na dinamiko kavitacijskega vrtinca v sesalni cevi francisove turbine.

Dinamika kavitacijskega vrtinca je bila merjena z metodo vizualizacije. Predstavljena je metoda, s katero je mogoče napovedati dinamiko kavitacijskega vrtinca na podlagi izmerjenih tlačnih utripanj v eni točki na steni sesalne cevi. Uspešnost napovedi je bila v povprečju zelo dobra.
