Large Eddy Simulation,ation. The form presented below is a simplification of these equations for incompressible flows and a constant viscosity. For a detailed derivation of the Navier-Stokes equations as well as the simplifications applied for incompressibility, many textbooks on fluid dynamics are available, eg. , or .

Unresolved Issues,tion. The velocity values inside the cooling hole were increasing beyond the stability limit given by the CFL condition, therefore causing the simulation to abort. This phenomenon could be observed on different grids and even at very low timesteps which lead to the conclusion that it is not just a matter of stability but a bug in the code.

Introduction,ly if the software tools are enhanced along with the hardware improvements. The focus of this work lies on improving a previously developed solver (see ) to be used for the simulation of highly turbulent flows using a method known as large eddy simulation (LES).

Introduction,In recent years the computational power of computers and the availability of large parallel clusters have drastically increased and with that, simulations have become more and more complex. This allows for more detailed studies of physical phenomena in challenging environments and geometries, but on

Large Eddy Simulation,mulations for the conservation of momentum, energy and mass, therefore leading to three momentum equations, one energy equation and one continuity equation. The form presented below is a simplification of these equations for incompressible flows and a constant viscosity. For a detailed derivation of
