Curriculum Introduction to fluid dynamics in water turbines

2 hp (ECTS)

Time: 19-21 October 2022

Objectives: To gain basic knowledge about water turbines and their fluid mechanics' aspects. After completion of the course the student will:

  • know the fundamental of fluid mechanics in turbomachinery
  • understand the basics of design and analysis of water turbines
  • be familiar with dimensional analysis and scaling effects of water turbines
  • be able to make a global estimation of the turbine system, using the Bernoulli equation
  • have the basic knowledge about the cavitation process in water turbines and how to avoid it
  • know the basics of how to study water turbines using Computational Fluid Dynamics (CFD)


  • Introduction and background
  • Water turbine types and their operating ranges
  • Basic principles
  • Dimensional analysis and scaling effects
  • Losses and flow imperfections
  • Cavitation
  • Principles of CFD in water turbines
