This article presents results of the experimental measurements of the cavitation phenomena in a Venturi tube with water as the working medium. Three variants of such tube were tested. Angles of converging and diverging sections are equal to 45o and 45o, 30o and 60o, 45o and 60o, respectively. In every case the throat diameter is equal to 3 mm and the throat length to 6 mm. The average flow velocity ranges from 0.1 to 0.5 m/s. During measurements, the average flow velocity, upstream and downstream pressure and water temperature were recorded. Additionally, by the use of a high-speed camera and a simple digital camera, information about the size and the shape of the bubble clouds for different flow conditions was collected. The aim of the article is data acquisition for the further numerical analyses. The experimental runs executed for this paper are to help provide more information about this type of flow, since numerical modeling of the cavitation phenomena in Venturi tubes is still very difficult and in many cases even quantitative agreement is impossible to obtain.
