A Computer Aided Engineering Approach in the Design of Impellers

Computerized Aided Engineering (CAE) techniques currently used in the design of impellers is presented. Both computerized flow performance analysis and structural integrity analysis methods are discussed. Computer graphic capabilities used in the design cycle are also listed. An approach to evaluate the structural integrity of impellers under steady state and dynamic loading is given. Correlation between analytical and test results is presented. The emphasis of the paper is placed on the structural integrity aspects.
