Alaiz

Alaiz Neutral
ScopeThe benchmark is open to participants of the Wakebench project using flow models over topography in neutral conditions. This benchmark is a follow up of the sensitivity analysis (Alaiz_Sensitivity) to validate the results in neutral conditions.ObjectivesProduce the best estimate of the flow field in neutral conditions above the Alaiz site for the North and South wind directions.

Alaiz Sensitivity
ScopeThe benchmark is open to participants of the Wakebench project using flow models over topography in neutral conditions. This initial benchmark will carry out an assessment of the sensitivity to modeling criteria that is adopted when approaching the simulation of a realistic site for wind farms in complex terrain. In order to simplify the analysis, only the North and South wind direction sectors will be analyzed.

Askervein

Askervein Neutral
ScopeThe benchmark is open to participants of the Wakebench project using flow models over topography in neutral conditions. The study will show the changes in the mean flow field above the Askervein hill for different incident flow angles defined by the following wind directions:

DU00W212_High-Reynolds

AVATAR 2D High Reynolds
ScopeWithin the AVATAR project 2D airfoil measurements have been taken in the wind tunnel at conditions similar to the conditions of 10MW+ turbines. The pressurized DNW HDG wind tunnel measurements have been carried out on a DU00-W-212 airfoil where the pressurized environment enabled Reynolds numbers up to 15M (note that the high tunnel pressures allow such high Reynolds numbers to be taken at a relatively low Mach (M) number of say 0.1 in correspondence with wind turbine conditions).

Axisymmetric Wake

Axisymmetric Wake Neutral
ScopeThe benchmark is open to participants of the Wakebench project using flow models to calculate wind turbine wakes. Completion of the benchmark will demonstrate that a simulation approach is capable of capturing the physics necessary to predict behavior of an isolated wake.ObjectivesEvaluate models using a theoretical solution to assure that they can capture an important component of wind turbine wake flows.
