Curvilinear element of the discontinuous Galerkin method designed to capture the labyrinth seal geometry exactly

Autor: Bublík O., Pecka A., Vimmr J.

Publikováno v: Applied and Computational Mechanics, Vol 16, Iss 1, Pp 5-22 (2022)

The present study applies the discontinuous Galerkin finite element method to a numerical simulation of a compressible fluid flow through a labyrinth seal. This paper is proposes a curvilinear hexahedral element, which is deformed in such a way that

A comparative study of 1D and 3D hemodynamics in patient-specific hepatic portal vein networks

Autor: Jonášová A., Bublík O., Vimmr J.

Publikováno v: Applied and Computational Mechanics, Vol 8, Iss 2, Pp 177-186 (2014)

The development of software for use in clinical practice is often associated with many requirements and restrictions set not only by the medical doctors, but also by the hospital’s budget. To meet the requirement of reliable software, which is able

Numerical analysis of bypass model geometrical parameters influence on pulsatile blood flow

Autor: Jonášová A., Vimmr J., Bublík O.

Publikováno v: Applied and Computational Mechanics, Vol 5, Iss 1, Pp 29-44 (2011)

The present study is focused on the analysis of pulsatile blood flow in complete idealized 3D bypass models in dependence on three main geometrical parameters (stenosis degree, junction angle and diameter ratio). Assuming the blood to be an incompres

Contribution to the gas flow and heat transfer modelling in microchannels

Autor: Hajžman M., Vimmr J., Klášterka H.

Publikováno v: Applied and Computational Mechanics, Vol 3, Iss 1, Pp 63-74 (2009)

This study is focused on the mathematical modelling of gas flow and heat transfer in a microchannel with the rectangular cross-section. The gas flow is considered to be steady, laminar, incompressible, hydrodynamically and thermally fully developed.

On the modelling of compressible inviscid flow problems using AUSM schemes

Autor: Hajžman M., Bublík O., Vimmr J.

Publikováno v: Applied and Computational Mechanics, Vol 1, Iss 2, Pp 469-478 (2007)

During last decades, upwind schemes have become a popular method in the field of computational fluid dynamics. Although they are only first order accurate, AUSM (Advection Upstream Splitting Method) schemes proved to be well suited for modelling of c

Analysis of blood flow through a three-dimensional bypass model

Autor: Vimmr J., Jonášová A.

Publikováno v: Applied and Computational Mechanics, Vol 1, Iss 2, Pp 693-702 (2007)

The purpose of this study is to analyze the steady laminar blood flow through a complete idealized threedimensional bypass model with regard to the bypass hemodynamics and to compare the obtained results with the ones from the two-dimensional model.
