Analytical analysis of cavitating flow in Venturi tube on the basis of experimental data

The content of this article is a direct continuation of the prior experimental works on the topic of cloud cavitation in Venturis. The results of the experimental tests were used to create a set of characteristics for three types of Venturis. The article has two aims: 1) verification of the similarity between the characteristics obtained and reported in the literature, 2) verification of the range of the obtained characteristics with respect to parallel diagrams. Both aims were achieved, which confirms that the quality of the prior results of the experimental measurements is at least sufficient to realize the main objective of the whole project: creation of numerical models of cavitating flow in Venturis. The literature overview showed that the issue has been not solved until today, even at the qualitative level. This reason was the motivation for the undertaken research, including contents of the article.
