Abstract

The erosion in different types of turbines is discussed. The reasons why Francis turbines are less beneficial with respect to erosion than Pelton or Kaplan turbines are explained. New technologies such as CFD-simulation including numerical prediction of relative erosion intensities and advanced coating applications are shown. The examples out of the experience of VATECH HYDRO cover all types of turbines in various continents (Europe, South America, Asia). With up-to-date know-how in abrasion research a further exploration of Hydro power also in highly silt-laden rivers can be promoted.
