Fast Iterative Methods for Navier-Stokes Equations with SST Turbulence Model and Chemistry
نویسنده
چکیده
The steady state compressible Navier-Stokes equations are solved with an explicit Runge-Kutta scheme accelerated by multigrid and an implicit preconditioner. Extensions are made to include a k-ω/SST turbulence model and chemical reactions. The implicit smoother enables the use of high CFL numbers yielding fast convergence. We present applications to turbulent solutions for flows about wings and plumes and for flows with several chemical reactions.

Performance of SST k-ω Turbulence Model for Computation of Viscous Drag of Axisymmetric Underwater Bodies
This paper presents 2-D finite volume method for computation of viscous drag based on Reynolds-averaged Navier-Stokes (RANS) equations. Computations are performed on bare submarine hull DREA and six axisymmetric bodies of revolution with a number of length-diameter (L/D) ratios ranging from 4 to 10. Both structured and unstructured grids are used to discretize the domain around the bodies. Diff...
متن کاملReynolds-Averaged Navier-Stokes Simulation of a 2D Circulation Control Wind Tunnel Experiment
Numerical simulations are performed using a Reynolds-averaged Navier-Stokes (RANS) flow solver for a circulation control airfoil. 2D and 3D simulation results are compared to a circulation control wind tunnel test conducted at the NASA Langley Basic Aerodynamics Research Tunnel (BART). The RANS simulations are compared to a low blowing case with a jet momentum coefficient, Cμ, of 0.047 and a hi...

This reports the study on the flow behaviour, heat transfer and contamination distribution in a room. For this purpose the 3-D incompressible Navier-Stokes equations, energy equation and a mass transfer equation which model the concentration of contamination have been applied. For turbulence simulation the two equation standard k- turbulence model was employed. By means of SIMPLE algorithm the...

In this study, the results of parallelization of a 3-D dual code (Thin Layer, Parabolized Navier-Stokes solver) for solving supersonic turbulent flow around body and wing-body combinations are presented. As a serial code, TLNS solver is very time consuming and takes a large part of memory due to the iterative and lengthy computations. Also for complicated geometries, an exceeding number of grid...
متن کاملIterative Substructuring Methods for Indoor Air Flow Simulation
The numerical simulation of turbulent indoor-air flows is performed using iterative substructuring methods. We present a framework for coupling eddyviscosity turbulence models based on the non-stationary, incompressible, nonisothermal Navier-Stokes problem with non-isothermal near-wall models; this approach covers the k/ǫ model with an improved wall function concept. The iterative process requi...
