Project profile

There are shortcomings of the traditional velocity coefficient method, which mainly depends on the experience of the designer, and the similar design mainly depends on the model pump, which are both difficult to improve the performance of the pump. A method based on the combination of CFD technology and modern optimization technology is developed to effectively provide the performance of the pump according to the three-dimensional turbulent flow. It can not only optimize the centrifugal pump according to the performance requirements under multiple working conditions, but also improve its weighted average efficiency and expand its high efficiency zone.
