Optimization of hydraulic turbine diffuser

open access: yesEPJ Web of Conferences, 2016
Hydraulic turbine diffuser recovers pressure energy from residual kinetic energy on turbine runner outlet. Efficiency of this process is especially important for high specific speed turbines, where almost 50% of available head is utilized within diffuser.
