RISAnalysis of the Runner Behavior During the Start-Up Sequence in a Bulb Turbine Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental analysis of the start-up sequence of a bulb turbine was performed in a closed-loop circuit, and analyses of global performances were conducted under three start-up conditions. In order to conduct a deeper ...
Experimental Study of a Bulb Turbine Model During Start-Up and at Speed-No-Load Conditions, Based on the Measurement of Unsteady Pressure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental analysis of a bulb turbine during the start-up sequence and in speed-no-load (SNL) operating conditions was performed in a closed-loop circuit. This study focuses on pressure fluctuations across the machine. ...
The Measured Flow at the Inlet of a Francis Turbine Runner Operating in Speed No-Load Condition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For Francis turbines, speed-no-load (SNL) represents one of the most detrimental operating conditions, marked by significant pressure and strain fluctuations on the runner. Mitigating these fluctuations necessitates a ...
