Blade-resolved CFD simulations of a periodic array of NREL 5 MW rotors with and without towers

Ma, Lun; Delafin, Pierre-Luc; Tsoutsanis, Panagiotis; Antoniadis, Antonis F.; Nishino, Takafumi (MDPI, 2022-01-14)

A fully resolved (FR) NREL 5 MW turbine model is employed in two unsteady Reynolds-averaged Navier–Stokes (URANS) simulations (one with and one without the turbine tower) of a periodic atmospheric boundary layer (ABL) to ...
Comparison of low-order aerodynamic models and RANS CFD for full scale 3D vertical axis wind turbines

Delafin, Pierre-Luc; Nishino, Takafumi; Athanasios, Kolios; Lin, Wang (Elsevier, 2017-03-21)

A Double Multiple Streamtube model, a free-wake vortex model (both widely used for vertical axis wind turbine design) and RANS CFD simulations are used in this work to predict the performance of the 17 m Vertical Axis Wind ...
Effect of the number of blades and solidity on the performance of a vertical axis wind turbine

Delafin, Pierre-Luc; Nishino, Takafumi; Wang, Lin; Kolios, Athanasios (IOP Publishing: Conference Series / Institute of Physics (IoP), 2016-10-03)

Two, three and four bladed phgr-shape Vertical Axis Wind Turbines are simulated using a free-wake vortex model. Two versions of the three and four bladed turbines are considered, one having the same chord length as the ...
Momentum balance in a fully developed boundary layer over a staggered array of NREL 5MW rotors

Delafin, Pierre-Luc; Nishino, Takafumi (IOP Publishing, 2017-06-13)

3D Reynolds-averaged Navier-Stokes (RANS) simulations of a fully developed wind farm boundary layer over a staggered array of NREL 5MW turbines are presented. The turbine is modeled as an actuator disk and as a fully ...
Numerical study of airfoil stall cells using a very wide computational domain

Manni, Luca; Nishino, Takafumi; Delafin, Pierre-Luc (Elsevier, 2016-10-05)

The formation of stall cells over a NACA 0012 airfoil at a Reynolds number of one million has been investigated numerically, using unsteady Reynolds-averaged Navier–Stokes (URANS) and delayed detached-eddy simulation (DDES) ...
Structural optimisation of vertical-axis wind turbine composite blades based on finite element analysis and genetic algorithm

Wang, Lin; Kolios, Athanasios; Nishino, Takafumi; Delafin, Pierre-Luc; Bird, Theodore (Elsevier, 2016-06-02)

A wind turbine blade generally has complex structures including several layers of composite materials with shear webs, making its structure design very challenging. In this paper, a structural optimisation model for wind ...
