Wind Turbine CFD with ANSYS Fluent, Part 2/3

This is a practical guide to perform CFD simulations of a wind turbine with ANSYS Fluent (v19.1). However it is recorded real-time, so that a very coarse mesh is generated to save time. Most notably, blade leading and trailing edges are not adequately resolved. A much finer mesh, beyond the capability of typical PCs, must be created than the mesh shown in the video such that further refining the mesh does not change the results significantly. Moreover, validation against representative experimental data is required; either in-house experiments or experimental data of a similar turbine reported in the literature. Nevertheless, many engineers and/or students do not have powerful workstations, so the guidelines in this video may be used as a practical tool to assess performance of wind turbines, reserving above issues.

Thank you! Rahmat!

this analysis over-simplifies the calculation, because you assume a TSR of 4, but that value is unknown for a new turbine design

It is not simplification but rather a method. Rpm is determined by the generator and the wind. Apriori, you repeat the analysis at different tip speed ratios and then intersect it with the generator curve. Then you determine the rotational speed of the turbine as a function of wind speed. But specifying rotational speed apriori is to obtain the aerodynamic performance of the wind turbine. It is like determining chacteristics of a gasoline engine, which is not a simplification. But the operating line is a result of matching with the gearbox, which has a separate characteristics…
