	Numerical Simulatin of Flow Induced Vibrations Růžička, Martin ; Feistauer, Miloslav (advisor) ; Kozel, Karel (referee) ; Knobloch, Petr (referee) Detailed record
	Numerical Calculation of 2D Transonic Flow Over Profile Slouka, M. ; Kozel, Karel Mathematical models used in this work are based on the calculation of inviscid and viscous compressible transonic flow over the profile which is given 8% DCA blade cascade. Two different numerical models are used and compared with experimental measurements. Detailed record
	Numerical experiments with the turbulent flow through the DCA 8% cascade Trefilík, Jiří ; Kozel, Karel ; Příhoda, Jaromír The work is concerned with the development of a numerical method for a simulation of transonic turbulent flow and the simulation of the flow through the DCA 8% cascade. For turbulence modelling the algebraic Baldwin-Lomax model and the two-equation standard and modified (SST) models were employed and the numerical results are presented. Detailed record
	Numerical Solution of 3D Airflow in Channel Representing a Vocal Tract Pořízková, P. ; Kozel, Karel ; Horáček, Jaromír This study deals with the numerical solution of a 3D compressible flow of a viscous fluid in a channel for low inlet airfloe velocity. the channel is a simplified model of the glottal space in the human vocal tract. The system of Navier-Stokes equations has been used as mathematical model of laminar flow of the compressible viscous fluid in a domain. The numerical solution is implemented using the finite volume method (FVM)and the predictor-corrector MacCormack scheme with artifical viscosity using a grid of quadrilateral cells. Detailed record
	Numerical Solution of 2D Transonic Inviscid and Viscous Compressible Flow in Channel Slouka, M. ; Kozel, Karel The work deals with 2D numerical solution of the transonic inviscid and viscous compressible flow in the channel. Results are based on the solution of the system of Euler equations and Navier-Stokes equations with additional algebraic Baldwin-Lomax model of turbulence. Detailed record
	Numerical Simulations of Turbulent Transonic Flow Through a Cascade Trefilík, Jiří ; Kozel, Karel ; Příhoda, Jaromír In this paper some newly obtained results in the simulation of turbulent transonic flow through the 8% DCA cascade are presented and compared with previous results. The simulations are based on two different turbulence models and as a reference also calculations for inviscid fluid are included. Detailed record
	Numerical experiments modelling turbulent flows Trefilík, Jiří ; Kozel, Karel ; Příhoda, Jaromír The paper deals with modification of the transition model with the algebraic equation for the intermittency coefficient proposed originally by Straka and Příhoda (2010) for the bypass transition for modelling of the transition at low free-stream turbulence. The modification is carried out using accessible experimental data for the flat-plate flow. Further, the three-equation k-kL-omega model proposed by Walters and Cokljat (2008) was used for the modelling of the transition at low free-stream turbulence. Both models were tested by means of the incompressible flow around airfoils at moderate and very low free-stream turbulence. Detailed record
	Numerical solution of compressible subsonic flows in 3D channel Pořízková, P. ; Kozel, K. ; Horáček, Jaromír The channels shape is a simplified geometry of the glottal space in the human vocal tract. Goal is numerical simulation of flow in the channels which involves attributes of real flow causing acoustic perturbations. The system of Navier-Stokes equations closed with static pressure expression for ideal gas describes the unsteady laminar flow of compressible viscous fluid. The numerical solution is implemented using the finite volume method and the predictor-corrector MacCormack scheme with artificial viscosity using a grid of quadrilateral cells. The unsteady grid of quadrilateral cells is considered in the form of conservation laws using Arbitrary Lagrangian-Eulerian method. Detailed record
	Numerical simulation of turbulent transonic flow over a profile and through a cascade Trefilík, Jiří ; Kozel, K. ; Příhoda, Jaromír The contribution deals with the numerical simulation of transonic turbulent flow around the 18% thick circular-arc biconvex airfoil and through the 8% DCA turbine blade cascade. Numerical results for some test case configuration are presented and discussed. Detailed record
	Some Results of Simulations of 3D Backward Facing Step Louda, Petr ; Kozel, K. ; Příhoda, Jaromír The paper deals with numerical simulation of 3D incompressible flow over backward facing step. The RANS technique is used with an explicit algebraic Reynolds stress turbulence model. The numerical solution is achieved by implicit finite volume method. The results are compared with measurement.
