  • Airfoil - an overview | ScienceDirect Topics
    Airfoil is a cross-section of a wing or blade; thus, it is a two-dimensional shape A typical airfoil and its main terminology are shown in Fig 3 1 When an airfoil is located in a fluid flow, as shown in the figure, its first point that hits the wind is called the leading edge (assuming that wind blows from left to right) Similarly, the last point of the airfoil on which the wind leaves the
  • Aerodynamic performance characteristics of low Re airfoils: A . . .
    This research aims at investigating the aerodynamic performance of 51 low Re airfoils and applying a Multi Criteria Decision Making (MCDM) approach fo…
  • Airfoils optimization based on deep reinforcement learning to improve . . .
    In this paper, we propose an optimization framework for rotor airfoils based on DRL technology First, a surrogate model for predicting the aerodynamic coefficient hysteresis loops of the airfoils is built by a deep neural network (DNN) to reduce the cost of flow field computations
  • Aerodynamic performance comparison of airfoils suggested for small . . .
    For the present study, different kinds of airfoils suggested for small horizontal axis wind turbines were selected from the wind turbine database and published literature The selected airfoils were analysed using QBlade software for different Reynolds numbers (Re) and angles of attack (AoA)
  • Aerodynamic characteristics of wind turbine blade airfoils
    The development of a new generation of dedicated wind turbine airfoils started in the mid-1980s with the designs of the S8xx airfoils by Somers and Tangler 2 These researchers were followed by Björck, 3 Timmer and van Rooij 4 and Fuglsang and Bak 5, 6 More recently, van Dam 7 and other researchers in the USA presented so-called flatback airfoils for the inner part of the blade
  • Airfoil - an overview | ScienceDirect Topics
    Wings, foreplanes, canards, rearplanes, and tails are all airfoils An airfoil section is the profile of an airfoil when sliced from leading to trailing edge Airplane (aeroplane, from Gk: αερo-πλανoσ, a wanderer in the air) a mechanically propelled, heavier than air flying machine, with supporting surfaces fixed for flight
  • Aeroelasticity of membrane airfoils and flexible-chord airfoils with . . .
    This work is concerned with the aeroelasticity of permeable flexible airfoil and membranes; therefore, this section provides a literature review on the aerodynamics and aeroacoustics of permeable airfoils,and also a review on the aeroelasticity of impermeable membrane and flexible airfoils
  • Aerodynamic performance characteristics of EYO-Series low Reynolds . . .
    This Re range is the typical range small wind turbines encounter during normal operation [44] The results of this study highlight important aerodynamic performance parameters of the EYO-Series airfoils and benchmark for the development of other low Re airfoils The methodology used to undertake this study is presented in the following section
  • Ice accretion and aerodynamic effects on a multi-element airfoil under . . .
    Multi-element airfoils with very small gaps complicate not only the general flow structures but also the generation of the computational mesh In particular, the boundary layer transition, flow separation, and interaction of wakes can cause severe computational challenges in the simulation of multi-element airfoils
  • Aerodynamic performance comparison of airfoils suggested for small . . .
    The objective of the present research work is to identify a suitable airfoil for the design of a small horizontal axis wind turbine For the present s…
