Hydrodynamic cavitation in Venturi channels with different divergent angles [PDF]
Journal on Processing and Energy in AgricultureHydrodynamic cavitation occurs in hydraulic systems when flow restrictions increase velocity and decrease pressure below vapor pressure. To study cavitation phenomena, simplified geometries such as Venturi channels are commonly used for experiments and ...

A Study on the Repeatability of Cavitation Tunnel Tests
Journal of the Society of Naval Architects of Japan, 1968 In order to understand the level of the accuracy and the repeatability of cavitation tunnel tests, a propeller model was tested repeatedly in cavitation tunnel and in open-water. The test results were analyzed in terms of the variation of thrust and torque at each set of advance constant and cavitation number. From the test results and the analysis, it

Propeller Cavitation in Non-Uniform Flow and Correlation with the Near Pressure Field
Journal of Marine Science and Engineering, 2016 An experimental study is carried out in a cavitation tunnel on a propeller operating downstream of a non-uniform wake. The goal of this work is to establish quantitative correlations between the near pressure field and the cavitation pattern that takes ...

Experimental study of appearance of thermodynamic effect on cavitation in hot water
Nihon Kikai Gakkai ronbunshu, 2017 In this study, in order to clarify a relation between thermodynamic effect, which suppresses cavitation, and scale effect, which promotes cavitation, tunnel experiment was done with NACA16012 single hydrofoil in hot water.
