Abstract EN
A model water turbine draft tube containing vortex generators (VG) was studied.
Numerical simulations were performed to investigate 55 design variations of the vortex generators in a draft tube.
After analyzing the shapes of streamlines and velocity distributions in the tube and comparing static pressure recovery coefficients (SPRC) in different design variations, an optimum vortex generator layout, which can raise SPRC of the draft tube by 4.8 percent, was found.
To verify the effectiveness of the vortex generator application, a series of experiments were carried out.
The results show that by choosing optimal vortex generator parameters, such as the installation type, installation position, blade-to-blade distance, and blade inclination angle, the draft tube equipped vortex generators can effectively raise their SPRC and working stability.
