Turbulent Flow Approximation of 3D Flows in Channel: Application of Stabilized Finite Element Method
Original language description
In this paper the numerical approximation of three-dimensional incompressible turbulent flow in a channel is presented. The mathematical model based on Reynolds averaged Navier-Stokes equations is closed by the linear TNT k-omega eddy viscosity model. For the numerical approximation of RANS equations the stabilized finite element method is used. The streamline-upwind/Petrov-Galerkin and pressure stabilizing/Petrov-Galerkin method together with div-div stabilization is used. The flow velocity componentsand the pressure are approximated by continuous piecewise linear functions, the tubulent kinetic energy and specific dissipation rate are approximated by the stabilized finite element method, where non-linear stabilization method based on crosswind diffusion schemes is used. The first numerical results are presented.
