The paper gives a brief overview of the theory of the smoothed particle hydrodynamics (SPH). The SPH governing equations for incompressible flow of viscous fluid are derived. The presented SPH model is capable of simulating free surface flows involving fluid to fluid and fluid to rigid wall interactions. The results of performed numerical simulations are presented.

Im Beitrag ist kurzes Resümee der „Smoothed Particle Hydrodynamics" (SPH) Methode eingeführt. Hier sind die SPH Bewegungsgleichungen für inkompressible reibungsbehaftete Flüssigkeitsströmung ableitet. Dargestelltes SPH Modell ist für Simulierung der Strömung mit freier Oberfläche und für Flüssigkeitsinteraction und Interaction zwischen Flüssigkeit und feste Wand geeignet. SPH Ergebnisses der numerischen Simulierung sind dargestellt.
