In the article, validation of results of numerical simulations of cavitating flow in a convergent-divergent nozzle is presented. In validation, a new optoelectronic system is used in order to extract the changes in the bubbles volume fraction of the mixture in freely specified cross-sections. Three homogeneous models (Schnerr and Sauer, Singhal et al. and Zwart et al.) are analysed. The assessment of usefulness of the new system in experimental measurements of cavitation is the main aim of the article. Looking for new opportunities to replace image analysis, which is a traditional validation method in numerical simulations of cavitating flows, is motivation for the research. The results obtained with the use of the system show a good agreement with the simulation’s results for the two chosen cross-sections. The described optoelectronic system gives promising results and can be regarded as an alternative to traditional validation methods in the cavitation research area.
