【Abstract】 The testing methods for pressure fluctuation and forced air admission in the draft tube of a prototype Francis turbine are described. The relationships between the amplitude of pressure fluctuation and gate opening (or output) and discharge of air admission are discussed on the basis of the test results, with a preliminary survey on the determination of optimum discharge of air admission.更多还原
