Unsteady flow in pipeline
Šrenk, David ; Fialová, Simona (referee) ; Himr, Daniel (advisor)
The thesis deals with unsteady flow in the pipeline. Only one component of velocity is dominant in piping, so the problem is simplified to one-dimensional. Bachelor thesis has an analytical basis in partial differential equations of hyperbolic type. The problem and types of numerical methods are also numerically described. The numerical methods describe the boundary conditions and properties of the given methods.

Meshless modelling of fluid flow
Prochazková, Zdeňka ; Zatočilová, Jitka (referee) ; Čermák, Libor (advisor)
The thesis focuses on the Smoothed Particle Hydrodynamics (SPH) meshfree method. In the thesis, basic equations needed for solving fluid flow problems are derived - continuity equation, momentum equation and energy equation. The text presents the basic principles of the method, selection of a smoothing function, spacial discretization and a suitable time integration method. As an example of usage, the thesis models the shock tube problem. On this problem, we can compare the solution using the SPH method with the accurate solution.
