TI  - Numerical investigation of the effects of design parameters on hydraulic turbine guide vane design
AB  - Francis type hydraulic turbines that have a wide range of operatingrange for head and flow rates are commonly used in hydropowergeneration. Every power plant needs its custom designed turbinebecause the available head and flow rates, which are the mainparameters to start the design process, are different for each plant.Guide vanes are the only movable parts of Francis turbines. They controlthe flow rate through the turbine. In this study, a generalizedComputational Fluid Dynamics (CFD) aided design methodology isdeveloped and applied to the design of the turbines of two differentpower plants. The effects of several parameters, including the shape ofthe guide vane profile, eccentricity, blade angles, overlappingpercentage of the blades, number of guide vanes, and rotor-statordistance are examined. Results are investigated for each parameter interms of flow physics and important outcomes are determined forturbine designers.
