Analysis of offshore wind spectra and coherence under neutral stability condition using the two LES models PALM and SOWFA
Ning, Xu; Krutova, Maria; Paskyabi, Mostafa Bakhoday (Journal article; Peer reviewed, 2021)The Parallelized Large-Eddy Model (PALM) and the Simulator for Wind Farm Applications (SOWFA) have been used to simulate the marine boundary layer flows under neutral stability condition. The present work aims to investigate ... -
Development of an automatic thresholding method for wake meandering studies and its application to the data set from scanning wind lidar
Krutova, Maria; Paskyabi, Mostafa Bakhoday; Reuder, Joachim; Nielsen, Finn Gunnar (Journal article; Peer reviewed, 2022)Wake meandering studies require knowledge of the instantaneous wake evolution. Scanning lidar data are used to identify the wind flow behind offshore wind turbines but do not immediately reveal the wake edges and centerline. ... -
Evaluation of Gaussian wake models under different atmospheric stability conditions: Comparison with large eddy simulation results
Krutova, Maria; Bakhoday Paskyabi, Mostafa; Reuder, Joachim; Nielsen, Finn Gunnar (Journal article; Peer reviewed, 2020)The calculation of the velocity deficit in the wake of individual wind turbines is a fundamental part of the wind farm analysis. A good approximation of the wake deficit behind a single wind turbine will improve the power ... -
On Stochastic Reduced-Order and LES-based Models of Offshore Wind Turbine Wakes
Bakhoday Paskyabi, Mostafa; Krutova, Maria; Nielsen, Finn Gunnar; Reuder, Joachim; Guernaoui, O. EL. (Journal article; Peer reviewed, 2020)In this paper, the primary objective is to investigate flow structures in the wake of wind turbines based on applying a truncated Proper Orthogonal Decomposition (POD) approach. This scheme decomposes the three-dimensional ...
