An Actuator Sector Model for Wind Power Applications: A Parametric Study

Autor: Mohammad Mehdi Mohammadi, Hugo Olivares-Espinosa, Gonzalo Pablo Navarro Diaz, Stefan Ivanell

This paper investigates different actuator sector model implementation alternatives and how they compare to actuator line results. The velocity sampling method, tip correction, and time step are considered. A good agreement is seen between the line a

Actuator line simulations of wind turbine wakes using the lattice Boltzmann method

Autor: Henrik Asmuth, Hugo Olivares-Espinosa, Stefan Ivanell

Publikováno v: Wind Energy Science, Vol 5, Pp 623-645 (2020)

The high computational demand of large-eddy simulations (LESs) remains the biggest obstacle for a wider applicability of the method in the field of wind energy. Recent progress of GPU-based (graphics processing unit) lattice Boltzmann frameworks prov

The aim of the present work is to obtain a better understanding of how to model the thermally stratified wind field over a forest during full diurnal cycles. The setup of the study assumes a horizontally homogeneous forest, with the objective of find

Investigation of Turbulence Accuracy When Modeling Wind in Realistic Forests Using LES

Autor: Johan Arnqvist, Hugo Olivares-Espinosa, Stefan Ivanell

Publikováno v: Springer Proceedings in Physics ISBN: 9783030221959

This study presents an evaluation of wind field simulations, in neutral atmospheric conditions, above a heterogeneous forest. The calculations were performed with Large-Eddy Simulation (LES) code OpenFOAM, with explicit modelling of the forest throug
