【 摘 要 】

This paper presents the experimental data of the measured velocity field of a water and air-water system within a laboratory flotation chamber at various rotational speeds of the rotor and aeration. These results were used to verify the gas-phase distribution in the flotation chamber of a process conducted under specified hydrodynamic and physicochemical conditions. The PIV technique was used to determine the flow field in a number of planes; with this method non-invasive measurements of the velocity field in single and two-phase systems were carried out. An analysis of the results allows one to determine the parameters describing the hydrodynamic conditions in the flotation chamber and evaluate the effectiveness of the flotation process.
