Description	Fundamentals of two different numerical approaches to the fluid flow modelling are presented. The smoothed particle hydrodynamics (SPH) is a meshless approach,while the finite volume (FV) method is defined on a grid. Within SPH, the computational grid is replaced by a finite set of interpolating points. The fluid flow is described by Euler equations and dissipative effects are treated by artificial viscosity terms. Within the cell-centred FV method,the computational domain is discretised with a structured grid and the fluid flow is defined by a non-linear conservative system of the Navier–Stokes equations. The artificial dissipation and the algebraic turbulence model are applied. Implemented SPH and FV codes are tested on a two-dimensional flow of Newtonian fluid through a rigid channel.

(en) Tento článek se zabývá základy dvou rozdílných přístupů k modelování proudění tekutin. Metoda smoothed particle hydrodynamics (SPH) reprezentuje bezsíťový přístup, zatímco metoda konečných objemů (FV) využívá výpočetní sítě. V rámci metody SPH je výpočetní síť nahrazena konečnou množinou interpolačních bodů. K popisu proudění kapaliny se používá Eulerova rovnice a disipace je modelována pomocí umělé viskozity. V rámci FV metody je výpočetní oblast diskretizována za použití strukturované sítě a pohyb kapaliny je popsán systémem nelineárních Navier-Stokesových rovnic v konzervativním tvaru. Tento systém rovnic je rozšířen o model umělé disipace (cs)
