TL;DR: In this article, an extended analysis is presented which has been carried out with the final aim of identifying the most effective simulation settings to ensure a reliable fully-unsteady, two-dimensional simulation of an H-type Darrieus turbine.

TL;DR: In this paper, a numerical CFD analysis was carried out to characterize the flow field in the rooftop area of buildings with different shapes and geometrical proportions: the flow velocity modulus and direction were calculated for different oncoming wind profiles and the results were projected into a net available wind distribution in each building.

TL;DR: In this article, the authors evaluated the suitability, effectiveness and future prospects of simplified two-dimensional (2D) simulations for wind turbine performance analysis and showed that these simulations are able to provide accurate estimation of turbine performance and also reliably describe the attended flow-field around the rotor and its wake.

TL;DR: In this article, a multivariate sensitivity analysis was carried out on a specific case study at different tip-speed ratios in order to define the optimal mesh and timestep sizes needed for an accurate simulation.

TL;DR: In this paper, a Navier-Stokes CFD code featuring a very high parallel efficiency was used to thoroughly investigate the three-dimensional unsteady aerodynamics of a Darrieus rotor blade.
