The Danube Delta dynamics formation and expansion represent the motivation of the study included in this paper. The results of soil studies made possible to develop the Danube Delta genesis maps [7]. That information?s are the input data and the validation data for the numerical flow studies of the Danube River. The study of the formation of new territories has been developed by the Computational Fluid Dynamics (C.F.D.) method. There were modelled in three dimensions the maps for Danube River Basin flowing into th...

The aim of this paper is to present results of numerical analysis of a bird model impact with a helicopter windshield. It appears that the research findings which take into consideration the bird?s shape differ from those using a simplified bird model in the shape of a cylinder or a sphere. Overall, at higher speeds the windshield becomes pierced and its damage process occurs in a different manner. In order to conduct an analysis of a bird impact onto an aircraft windshield, we used the LS_DYNA software package. A...
