Abstract

Abstract

A mathematical model of the unsteady flow pipe section has been built up while CWS is transported in a long pipe. By solving the model, length of the unsteady flow pipe section, pressure gradient at every cross-section and the gross energy losses can be predicted. Through a small modification of the model the transition process of the pressure gradient in response to a sudden change of flow quantity may be revealed. Experimental results proved the model's reliability.
