Large Eddy Simulations of the free convective boundary layer

In the last decades an increasing interest in offshore wind energy has been observed. The main reason for ’going offshore’ may be the higher and more constant wind resource at sea than on land, leading to a higher energy production per wind turbine. Nevertheless to properly install wind farms is necessary to study the offshore conditions of each possible location. The limited knowledge about offshore conditions, compared to onshore conditions, motivates the use of numerical methodologies to study the offshore boundary layer.

Large Eddy Simulations over Oklahoma City

The continuous increase in computational resources is enabling the application of high fidelity turbulence modeling approaches to atmospheric flow simulations. This section is dedicated to a large-eddy simulation study that we performed for Oklahoma City. We considered a unique dominant wind direction. The results are compared to the nominal RANS results and the field experiment data to determine the benefits and challenges of large eddy simulations for these complex flow problems.
