CFD model of modulated water jet
Foldyna, Josef ; Sitek, Libor
In this paper, results of CFD simulation of modulated jet break-up in the air are presented. The results are compared with results of visualization of modulated jets obtained in the laboratory experiments. In addition to that, results of simulation of modulated jet impact onto flat perpendicular surface are compared with laboratory measurement of stagnation force of modulated jet.

Náročné uplatnění iteračních řešičů v geotechnice
Blaheta, Radim ; Byczanski, Petr ; Jakl, Ondřej ; Kohut, Roman ; Kolcun, Alexej ; Krečmer, Karel ; Starý, Jiří
In many fields of science and engineering, we can see challenging tasks, which require application of mathematical modelling. The physical phenomena are simulated with the aid of the finite element method and this simulation leads to huge computational demands, which are concentrated mainly to the solution of large-scale systems of equations. For such systems, we need high performance iterative solvers.

Iterační metody , předpodmínění a numerické řešení parciálních diferenciálních rovnic. Sborník konference věnované jubileu Owe Axelssona
These proceedings contain extended abstracts of the contributions delivered to the conference Iterative methods, preconditioning and numerical PDEs (IMET 2004) held in Prague. The topics of the conference are motivated ny mathematical modelling in science and engineering, which lead to a great interest in discretization methods and solution of the arising systems of linear or nonlinear equations. The advances in numerical simulations strongly depend on the achievements in both efficient numerical solution methods and in using high performance (parallel) computers. The recent trends and progress in numerical solution methods, mostly exploiting iterative techniques, are well documented by the conference papers.
