Design optimization method for Francis turbine

Optimization of GAMM Francis Turbine Runner

Nowadays, the challenge in hydraulic turbine design is the multi-objective design of turbine runner to reach higher efficiency. The hydraulic performance of a turbine is strictly depends on runner blades shape. The present paper focuses on the application of the multi-objective optimization algorithm to the design of a small Francis turbine runner. The optimization exercise focuses on the effic...

An Intelligent Optimization Method for Vortex-Induced Vibration Reducing and Performance Improving in a Large Francis Turbine

In this paper, a new methodology is proposed to reduce the vortex-induced vibration (VIV) and improve the performance of the stay vane in a 200-MW Francis turbine. The process can be divided into two parts. Firstly, a diagnosis method for stay vane vibration based on field experiments and a finite element method (FEM) is presented. It is found that the resonance between the Kármán vortex and th...

Cfd Approach for Prediction of Efficiency of Francis Turbine

Turbine is the most critical component in hydropower plants because it affects the cost as well as overall performance of the plant. Hence, for the cost effective design of any hydropower project, it is very important to predict the hydraulic behavior and efficiency of hydro turbines before they are put in actual use. Experimental approach of predicting the performance of hydro turbine is costl...

Blade Geometry Optimization for the Design of Wind Turbine Rotors

This paper describes a blade geometry optimization method for wind turbine rotors in which considerations are given to aerodynamics, structures, noise, and cost. An existing computer program named PROPGA, which is a genetic-algorithm based optimization method for wind turbines, provided part of the foundation for this work. The objective was to develop and implement structures and costs modelin...
