| Abstract: | Under lower load,the water pressure pulsation takes place for the unit 2 in Liu Jiaxia Hydraulic Power Plant.The partial differential equations of transient flow in the deformed penstock were derived.Their linearized solution is sought for the case when sinusoidal pulsation,happened at one end of the penstock.The experiment data is in good agreement with the analytic results for the unit 2.It is of importance theoretical and practical for the analysis of the stability of penstock,especially for that of the resonance of hydraulic turbine. |
