One of the key drivers to exploit their advantages is the use of accurate and efficient computational aerodynamic models during the design stage. The present work gives an overview of the performance of different state-of-the-art models. The following tools were employed, in descending order of complexity: (i) a blade-resolved Navier Stokes solver, (ii) a lifting line model, (iii) a vortex-based method coupling a near-wake model with a far-wake model, and (iv) two implementations of the widely used blade element momentum method (BEM), with and without radial induction. The predictions of the codes were compared when simulating the baseline geometry of a reference wind turbine and different tip extension designs with relatively large sweep angle and/or dihedral angle. Four load cases were selected for this comparison, to cover several aspects of the aerodynamic modeling: steady power curve, pitch step, extreme operating gust impact, and standstill in deep stall. The present study highlighted the limitations of the BEM-based formulations to capture the trends attributed to the introduction of curvature at the tip. This was true even when using the radial induction submodel. The rest of the computational methods showed relatively good agreement in most of the studied load cases. An exception to this was the standstill configuration, as the blade-resolved Navier-Stokes solver was the only code able to capture the highly unsteady effects of deep stall.","PeriodicalId":23689,"journal":{"name":"Wind Energy","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2022-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43341529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herr","doi":"10.1002/we.2786","DOIUrl":"https://doi.org/10.1002/we.2786","url":null,"abstract":"Summary Active trailing-edge technology is a promising application for localized load alleviation of large-diameter wind turbine rotors, accomplished using one or more control surfaces in the rotor blade’s outer region. This work focuses on identifying noise contributions from the ﬂap side-edge and the trailing edge in a laboratory condition. Measurements were conducted in the Acoustic Wind tunnel Braunschweig (AWB) at the German Aerospace Center’s (DLR) Braunschweig site. The small-scale model has a span of 1200 mm and a chord of 300 mm. The control surface, a plain ﬂap, has a span of 400 mm and a chord length of 90 mm. Far-ﬁeld noise was measured using a phased-microphone array for various ﬂow speeds, angles of attack and ﬂap deﬂection angles. For sound source identiﬁcation, two noise reduction addons were installed interchangeably: trailing-edge brush and ﬂap side-edge porous foam. Analysis of the far-ﬁeld noise reveals that, while changes to the ﬂap deﬂection angle alter the far-ﬁeld noise spectra, the trailing-edge noise remains the predominant noise source at deﬂection angles − 5 ◦ and 5 ◦ . No additional noise level was observed from the ﬂap side-edge within the measurable frequency range at these angles. The ﬂap side-edge noise has an increased role for frequency larger than 2 kHz for the larger ﬂap deﬂection angles of − 10 ◦ and 10 ◦ . Furthermore, numerical reproduction of the results will also be presented using the FMCAS (Fast Multipole Code for Acoustic Shielding) toolchain developed at DLR.","PeriodicalId":23689,"journal":{"name":"Wind Energy","volume":" ","pages":""},"PeriodicalIF":4.1,"publicationDate":"2022-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47047586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
