Experimental and Numerical Simulation Study on the Flow Characteristics of the Draft Tube in Francis Turbine

The flow characteristics of the draft tube of a Francis turbine have a significant influence on turbine stability. Numerical simulations were performed for a Francis turbine under three different output conditions of 20%, 100%, and 120% at the rated and maximum heads. Laser Doppler velocimetry (LDV)...
