Abstract:Meshless methods are getting more and more popular in order to numerically simulate
physical phenomena where an interface appears and plays an important role. Thanks to its
fully Lagrangian formalism, the smoothed particle hydrodynamics method (SPH) is hence
well suited to simulate free surface flows. The Pelton turbine is an hydraulic turbomachinery
whose flow is challenging to simulate because of the complex rotating geometry, the free
surface and the interaction between the runner and the casing. The work presented here
aims at adapting SPH to simulate such a flow. The standard SPH model has first been
successfully used to prove the capacity of the method in order to simulate flows in Pelton
turbines. As the prediction of the pressure field on the bucket's surface is a key issue, a
new simple model for the treatment of solid boundary conditions is proposed. Simulations of

industrial test cases, including a complete rotating runner, are finally shown. Reprinted by
