Abstract
The application of a novel turbulent inflow generator is presented using a 3D Direct Numerical Simulation (DNS) method. For simulation the in-house 3D CFD program Free Surface 3D (FS3D) is applied, which solves the incompressible Navier Stokes Equations for flows with free surfaces using a Volume-of-Fluid (VOF) technique. Three different numerical setups are presented, demonstrating the wide range of application of the new inflow generator. For chosen cases qualitatively comparisons are made between the new and a former implemented turbulence generator. Another more general focus is put on the high influence of turbulent flow fields on simulation outcomes, which justifies the use of computationally intensive inflow generators. Further, information about the performance on the NEC SX-8 platform, where all the simulations were performed, are revealed.
