The following operating conditions of the wind turbine were chosen for the validation: (1) Idling below the cut-in wind speed (2) Rotornacelle assembly (RNA) rotation maneuver below the cut-in wind speed (3) Power more » production below and above the rated wind speed and (4) Shut-down. Phase III of the OC5 project validates OWT models against the measurements recorded on Senvion 5M wind turbine supported by the OWEC Quattropod from the alpha ventus offshore wind farm.

The main objective of the Offshore Code Comparison Collaboration Continuation, with Correlation (OC5) project, is validation of aero-hydro-servo-elastic simulation tools for offshore wind turbines (OWTs) through comparison of simulated results to the response data of physical systems.

As new computing technologies mature, such as graphics processing unit (GPU)-based computing, the future of full wind plant flow modeling is exciting. We are also beginning to see the low- and high-fidelity tools used together to perform uncertainty quantification of energy estimates and optimization of wind plant layouts. We are beginning to see the expensive, high-fidelity tools being used to create data and knowledge that improves or enables the creation of new cheaper, lower fidelity tools. As computational resources become more readily available, it is even becoming common for turbine manufacturers to use CFD of some form to model wind plants in complex terrain to help in the wind turbine siting and selection process. Researchers use LESs of the wind plant to study phenomena such as wind turbine wake interactions with each other and with the atmospheric boundary layer (ABL). Wind plant layout designers run hundreds or thousands of simulations over all possible wind directions and speeds using simple models to predict a future wind plant's annual energy production. The uses of wind plant flow simulations are equally varied. There are many ways to model this type of flow, ranging from very simple models of wind turbine wakes and their interactions that can run in a matter of seconds on a laptop to high-fidelity, turbulence -resolving LES of the atmospheric flow and wakes that require days of use of thousands of cores on a high-performance computing cluster. For example, Figure 6.1 shows the computed flow field from a high-fidelity simulation of the Lillgrund offshore wind farm using computational fluid dynamics (CFD) with large-eddy simulation (LES) turbulence modeling and actuator more » line rotor aerodynamics models. This topic is interesting and exciting because of the increasing variety of and uses for wind plant flow modeling and simulation. The subject of this chapter is the modeling and simulation of the flow through full wind farms, also known as wind plants, which are collections of many wind turbines within a region working together to supply power to the grid like any other type of power plant. Tecplot uses the number of values on the first row to determine how many variables there are.= , You can change this from within Tecplot once the data is loaded. Tecplot will assume that the first variable is the X coordinate, the second the Y coordinate, and If your data is a simple plot, then you need only have it in a file with the values seperated by spaces or linebreaks. More information on preplot can be found in section 7.1 of the Tecplot manual. If you are going to be using the same set of data more than once or twice, it is probably best to run preplot so that you can load it more quickly. You can create a binary file from an ASCII file by running the program preplot on your data. Tecplot can either read ASCII (text) data files or data files in a Tecplot specific binary format. There, input files are gone over in more detail. If you are going to be loading in more than a few variables, or want to create a complex plot, then you are strongly encouraged to read chapter 6 of the Tecplot manual, available in the Barker Library stacks. However, it needs to have a fairly strictly formatted input file.
Tecplot can handle very complex input data.
