摘要：
This paper introduces a method of blade profile optimisation for Kaplan-type turbines, based on modelling the interaction between rotor and stator blades. Rotor and stator blade geometry is described mathematically by means of a midline curve and thickness distribution. Genetic algorithms (GA) are then used to find a global optimum that minimises the loss coefficient. This allows for variety of possible blade shapes and configurations. Artificial neural networks (ANN) are used for approximation due to long calculation time. The influence of draft tube on the loss coefficient is also investigated.
