Standard k-ε (SKE) and Large Eddy Simulation (LES) techniques were chosen as the turbulent model for the validation study.
Firstly, a steady state simulation using SKE was obtained and the steady state statistics was used as the initial conditions for the LES simulation.
The LES simulation is continued for 30 s of simulation time in order to establish the turbulent wind fields throughout the domain and all statistics are averaged at least for 15 s.
