Prediction of pump system dynamic behaviors considering impeller configuration and internal losses by bondgraphs

摘要

This is the second report of study on dynamic behaviors of a pump system by using Bondgraphs method. In this paper, the more detailed model of the system, bondgraphs on the dynamic behaviors has been established considering the influence of an impeller configuration and internal losses of the pump. Especially, the mathematical expressions of nonlinear internal losses of the pump are derived and their effects have been investigated.
