Despite advances in turbulence modelling, the Smagorinsky model remains a popular choice for large eddy simulation (LES) due to its simplicity and ease of use. The dissipation in turbulence energy that the model introduces, is proportional to the Smagorinsky constant, of which many different values have been proposed. These values have been...

This thesis concerns the industrial application of large eddy simulation to wind farm aerodynamics. Through a series of simple tests, it presents the pros and cons of using energy-conserving time integration and furthers the importance of a dissipation-free spatial discretisation. Finally, it demonstrates the capability of the Energy-Conserving...

A theoretical analysis is presented on the dependence of the standard and variational multi-scale Smagorinsky models on the proximity of the LES filter width Delta to the integral length scale of turbulence L on the one hand, and to the Kolmogorov scale eta on the other hand. Moreover modifications of the models are formulated, which respond...
