| Research Abstract |
Solid-liquid two phase flow pumps are widely used in Chinese industrial field. Many research on flow phenomena of solid and liquid in a pump impeller were carried out. There, however, has not been enough information on the relations of flow structure to pump performance. This research project was planned to make clear the flow phenomena and to establish the method of performance prediction by experimental and theoretical research. The experimental research was made at Kyushu Institute of Technology. Thinghua University took charge of theoreticalresearch.
In Kyushu Institute of Technology, pressure fluctuation measurement and flow visualization in a slurry pump impeller were carried out for variety of volumetric particle concentration, diameter and density. The pressure drop distribution and pressure fluctuation distribution were measured in an open impeller of slurry pump using phase-lock-averaging technique. Moreover, a nonuniform distribution of particle concentration was observed by use of CCD camera and picture processing technique. As a result of the present study, the relationship between pressure distribution and pump performance with flow rate were made clear from the experimental data.
In Thinghua University, the flow patterns in a centrifugal pump impeller was investigated by numerical flow analysis. The calculated pressure distribution was compared with the corresponding experimental data. and showed good agreement with measured one.
