This thesis examines sediment erosion in hydro turbines. A number of factors influence sediment erosion damage, including the sediment characteristics, turbine design and operating conditions, and materials used. Laboratory experiments and numerical simulations were conducted to better understand particle motion and separation within turbines. The simulations predicted erosion …
