Effect of turbulence intensity on the performance of an offshore vertical axis wind turbine
(Journal article; Peer reviewed, 2015)Offshore wind energy is one of the most competitive renewable energy resources available to us, which until now been under- exploited. Most of the problems associated with wind farm installation like land acquisition, low ... -
Implementation and comparison of three isogeometric Navier–Stokes solvers applied to simulation of flow past a fixed 2D NACA0012 airfoil at high Reynolds number
(Journal article; Peer reviewed, 2015)Implementation of three different Navier–Stokes solvers in an isogeometric finite element framework is presented in this paper. The three solvers Chorin projection method and Coupled formulation , both with the Spalart–Allmaras ... -
Investigation of the impact of wakes and stratification on the performance of an onshore wind farm
(Journal article; Peer reviewed, 2015)This work investigates the effects of wakes and stratification on the performance of turbines operating in the Bessaker wind farm. The wind farm is located in a highly complex terrain. Most dominant wind directions recorded ... -
Isogeometric methods for CFD and FSI-simulation of flow around turbine blades
(Journal article; Peer reviewed, 2015)Coupled fluid-structure interaction simulations of wind turbines have traditionally been considered computationally too expensive to carry out. However, more powerful computers and better solution techniques based on ... -
LES and RANS simulation of onshore Bessaker wind farm: analyzing terrain and wake effects on wind farm performance
(Journal article; Peer reviewed, 2015)This work compares the predictive performance of RANS and LES solver in capturing the effect of terrain and wakes on the performance of the Bessaker wind farm. This 25 turbine wind farm is located in a highly complex terrain ... -
Pre- and post-construction studies of conflicts between birds and wind turbines in coastal Norway (BirdWind) - Progress Report 2009
(Nina Rapport;505, Research report, 2009)From 2007 inclusive, NINA has received economic support for research on wind power and birds from the Norwegian Research Council (NFR) through the RENERGI-programme. The project is named Pre- and post-construction studies ... -
Simulation of airflow past a 2D NACA0015 airfoil using an isogeometric incompressible Navier-Stokes solver with the Spalart-Allmaras turbulence model
(Journal article; Peer reviewed, 2015)The work presented in this paper concerns the efforts of conducting a computational fluid dynamics (CFD) simulation of air flow past a fixed 2D NACA0015 airfoil at high Reynolds number (Re=2.5×106Re=2.5×106) using an ... -
Virtual Prototyping of a Low-Height Lifting System for Offshore Wind Turbine Installation
(Chapter, 2020)Due to the ever higher demands from the energy market, the quantity, dimension and power capacity of newly installed offshore wind turbines are continuously increasing. In terms of logistical management, economic feasibility ...
