Is Navier-Stokes based heterogeneous CPU/GPU computing suitable for wind turbine simulations?

In this study, Reynolds-averaged Navier–Stokes (RANS)-based heterogeneous CPU/GPU computing was introduced for full wind turbine simulations. A line-based solver on unstructured grids implemented on CPUs (HAMSTR) [ 10] was coupled to a structured solver implemented on GPUs (GARFIELD) [ 11] via a lightweight Python-based framework [ 12 ].

How can a CFD model predict a wind turbine?

Unlike a low-fidelity model, CFD simulations can accurately predict the boundary layer of a rotating blade and various unsteady flow features, such as a dynamic stall. In addition, using a transition model improves the performance prediction of a wind turbine by capturing the laminar–turbulent transition point along a boundary layer.

Can CFD simulations be used in a wind turbine?

On full wind turbine configurations, only a few studies have been conducted using high-fidelity CFD simulations because of the high computational costs and difficulties in generating a grid around complex geometries, such as a blade hub and a nacelle.

How is aerodynamic efficiency related to wind power generation efficiency?

The aerodynamic efficiency of a wind turbine is directly linked to its wind power generation efficiency. Therefore, wind turbine aerodynamics research has been conducted using low-fidelity models, such as actuator disk and line models [ 1] and the vortex-panel method [ 2 ], and high-fidelity computational fluid dynamics (CFD) simulations [ 3, 4 ].

Why do wind turbines have a higher fatigue load?

That is, flow fields in the wake region of wind turbine have smaller mean wind velocity and larger turbulence intensity. The fatigue loads of wind turbines in the near wake region would be larger owing to the strong spatial variations of the mean wind flow, which decrease as the increase of the distance to the former wind turbine.

Why is a wind turbine a flexible structure?

Wind energy, as one of the popular clean and renewable energy resources, plays an important role to produce electric power. To obtain larger energy output of the wind turbine, its size grows rapidly with long blades and slender tower; hence, the wind turbine is generally regarded as a flexible structure.
