| Abstract: | In this thesis, on the basis of N-S equation and standard turbulent flow model. Numerical simulation is given to turbulent flow inside impeller of LB50-160 type centrifugal pump. The results of the speed of flow field and pressure distribution in the impeller are obtained. Some important flow phenomena are found. They offer valuable information for the waterpower design of impeller. The finite element analysis is made to the structure of the impeller. It provides a basis for strength calculation of impeller |
