| Abstract: | The flow field in the screw centrifugal pump is simulated under the κ-ε two equation model by using the flow computing software Fluent. The distribution of the velocity, pressure, and flow inner clearance in the impeller and volute are discovered. Characteristics and the flow field in the screw centrifugal pump with single and double blade are compared. The affect of the blade number to the flow field in the screw centrifugal pump is analyzed. |
| Keywords: | screw centrifugal pump impeller interior flow field numerical simulation |
