Abstract

In this paper, a computational fluid dynamics (CFD)-based numerical simulation study is carried out for the transient characteristics of the pump turbine with the fast opening of the guide vane during the start-up of the energy storage condition. The dynamic mesh technology and user-defined function (UDF) of Fluent software are utilized to solve the Reynolds-averaged N-S equations in combination with the SST k-ω turbulence model, and the accuracy of the numerical simulation is verified by experimental data. The study analyzes the performance characteristics of the pump turbine at different stages from the time series, including the variation rules of flow rate, head and runner torque; reveals the dynamic evolution characteristics of the flow field during the opening process of the guide vane, especially the generation and dissipation mechanism of the high-pressure zone and vortex; visualizes the distribution of energy loss of the vane components in the start-up process based on the entropy production theory(EPT), which mainly arises from the Span0.0 and Span1.0 The frequency characteristics of pressure fluctuations in different parts and their influencing mechanisms were investigated by analyzing the pressure pulsation signals through the continuous wavelet transform (CWT), and the main influencing frequencies were 9 fn and 20 fn. The results of this study provide a research idea and a basis for the start-up of the pump turbine in the energy storage condition.
