An Automated Hydraulic Optimization Approach for RCP Impeller Using MOGA

Abstract

This paper presents an automated hydraulic optimization approach for impeller of a reactor coolant pump (RCP) combining a blade geometric modeller and parametric generator with automatic CFD solution procedure and multiobjective genetic algorithm. The approach depends on the cooperation between a genetic algorithm, a database and user defined objective functions and constraints which comprises hydraulic performances, structural and geometric constraint functions. In order to demonstrate the performance of the presented approach A mixed-flow RCP impeller was optimized.
