It is available to carry out numerical simulation and fluid dynamic analysis further. Based on Frozen-Rotor Approach and Rotor-Stator Approach, the numerical simulation was carried out in the centrifugal pump and the numerical results showed that the flow in the impeller and volute of centrifugal pump is periodically unsteady. Due to the interaction between impeller and volute the flow is characterized by pressure fluctuations and it is the strongest at impeller outlet and at the vicinity of the tongue. The unsteady pressure fluctuations are also one of the most important reasons to induce vibration and noise. Secondly, the flow field of the volute is characteristic of the vortex flow, and the vortex flow presents very complicated developing process which is creating, increasing and dissipating every now and then. All these lead to very large flow loss in the volute.

Also the multi-scale entropy processing and analysis of conductance fluctuating signals acquired by VMEA sensor for five flow patterns with water as the continuous liquid are conducted. The study result indicates that the increase of f o makes oil in water type slug flow occur at lower U sg; for low flow velocity, the continuous liquid inversion occurs at about f o=0.9 and the increase of U sg makes the inversion point move to low oil volume fraction; the multi-scale entropy detail describes the nonlinear dynamic characteristics of oil-gas-water flow patterns and the rate of MSE at low scales sensitively indicates the variation of flow patterns and can act as the efficient criterion of three-phase flow patterns identification.
