    • Simulation of Free Airfoil Vibrations in Incompressible Viscous Flow — Comparison of FEM and FVM 

      Autor: Sváček , Petr; Horáček , Jaromír; Honzátko , Radek; Kozel , Karel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      This paper deals with a numerical solution of the interaction of two-dimensional (2-D) incompressible viscous flow and a vibrating profile NACA 0012 with large amplitudes. The laminar flow is described by the Navier-Stokes ...

    • Synthesis of Mechanisms by Methods of Nonlinear Dynamics 

      Autor: Valášek , Michael; Šika , Zbynek
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      This paper deals with a new method for parametric kinematic synthesis of mechanisms. The traditional synthesis procedure based on collocation, correction and optimization suffers from the local minima of objective functions, ...

    • The Asymptotic Properties of Turbulent Solutions to the Navier-Stokes Equations 

      Autor: Skalák , Zdenek
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      In this paper we study the large time behavior of solutions to the Navier-Stokes equations. We present a brief survey of results concerning energy decay, and discuss a related phenomenon of the large time energy concentration ...

    • Transonic Flow of Wet Steam — Numerical Simulation 

      Autor: Halama , Jan
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)
      The paper presents a numerical simulation of the transonic flow of steam with a non-equilibrium phase change. The flow of steam is approximated by a mixture model complemented by transport equations for moments. Proper ...
