Presentation of the SPH method and models to Slovenian hydraulic research society (invited lecture at the SDHR)

The SPH method and the possibilities of its use in hydraulic modelling were presented to the interested professionals and scientists. The development of the model during the last couple of years and the potential usability of the SPH modelling tools in different fields of hydraulic research was shown. The title of the lecture, presented at the meeting of the Slovenian Association for Hydraulic Research (SDHR), was »Application of the SPH method to wave propagation due to water column collapse«.

Simulation of a laboratory dam break experiment with the SPH method and the analysis of the friction model

Evaluation of the boundary friction coefficient with respect to particle size. The results have shown that using the present formulation of the boundary friction, the friction coefficient should decrease with the particle size increasing.

Hydrodynamic and transport model of the inflow and outflow of cooling water of NPP Krško

Detailed measurements of flow velocities were carried out to test the validity of a 3D hydrostatic model PCFLOW3D. The model can well simulate flow conditions in the most part of the River. The results are less accurate in local regions where vertical velocity components exceed about 25 % of the horizontal velocities. A fully 3D model would be needed in such regions. The described model was extremely useful to determine thermal conditions in the Sava River and in future reservoirs. The article on this topic has been accepted for publication at the 34th IAHR Congress (Brisbane, June 2011).
