Ashrafizaadeh 9200559Turbulent flow around a tube bundle is simulated. Fully coupled Navier-Stokes equations in non-orthogonal coordinate system are solved employing a new multiblock parallel solver. For turbulent modeling, the Large-Eddy Simulation (LES) technique with the Smagorinsky subgrid eddy viscosity model is used. The discretized governing equations are second order in time and space and to prevent the pressure checkerboard problem, a Momentum Interpolation Method (MIM) is used. Parallelization of the computer code was done by a load balanced domain decomposition technique which results in a high computational efficiency and speed up. Flow pattern and characteristics are obtained for turbulent flow over five parallel tubes rows. Numerical results show a very good agreement with experimental results and reveal interesting flow behavior for such complicated industrial applications.]]>Thompson, B.E.,1985Davis, F.J. and Y.A.
