The optimizing method based on the numerical computation for passages of pump stations is the main direction in future. But the method has preferably put forward demand for visualization and simulation of its flow field. In this paper, the system and realized platform of visualization and simulation for suction box of pump stations have been designed, the results of visualization of flow velocity of sections, whole and local visualization of flow field of elbow draft tube as well as simulation of its flow field have been presented. The system can verify the characteristics of flow fields of suction box and give useful information to improve the design.
