Description: The conical diffuser (discharge cone), is an essential component of the hydraulic turbines, which converts the excess of kinetic head at runner outlet into static head, thus reducing the hydraulic losses in the draft tube. When the turbine operating far from the best efficiency point, the swirling flow in the discharge cone becomes unstable, with large pressure fluctuations and with increased of hydraulic losses. A new method for swirling flow control has been developed by Resiga et al. using a water jet injection along the cone axis. The present paper describes an efficient approach for supplying the control jet, using a flow-feedback method.
