A Collocation Method Utilizing Curvilinear Coordinates and Bézier Surfaces for Analysis of a Flow of Newtonian Liquids

Original language description

A new collocation method for analysis of a flow of Newtonian liquids based on application of curvilinear coordinates has been developed. The procedure arrives at division of the investigated region into quadrilateral domains and at approximation of the geometric, pressure, and velocity parameters by Bézier surfaces in each domain. These approximations are substituted into the Navier-Stokes equations and into the equation of continuity and the unknowns are the control points, the parametres defining theBézier surfaces. Their calculation strats from satisfying the Navier-Stokes equations and the equation of continuity at a specified number of collocation points whose positions in the domains are defined by curvilinear coordinates. Advantage of this approach is that no new discretization is needed if the shape of the investigated region is changed.

Czech description

Byla vyvinuta nová kolokační metoda pro analýzu proudění Newtonovských tekutin založená na aplikaci křivočarých souřadnic. Procedura rozděluje zkoumanou oblast na čtyřúhelníkové oblasti a v každé oblasti je založena na aproximaci geometrie, tlaku a rychlostních parametrů Beziérovými plochami.
