Geometry Design Optimization of a Wind Turbine Blade Considering Effects on Aerodynamic Performance by Linearization

https://www.mdpi.com/1996-1073/13/9/2320

For a wind turbine to extract as much energy as possible from the wind, blade geometry optimization to maximize the aerodynamic performance is important. In this study, the effects of these parameters on the aerodynamic performance of a wind turbine blade were examined. The analysis revealed that increasing the chord length and chord profile slope improves the aerodynamic efficiency at low wind speeds but lowers it at high wind speeds, and that the twist profile mainly affects the behaviour at low wind speeds, while its effect on the aerodynamic performance at high wind speeds is not significant. When the blade geometry was optimized by applying the linearization parameter ranges obtained from the analysis, blade geometry with improved aerodynamic efficiency at all wind speeds below the rated wind speed was derived. In this design procedure, the wind turbine blade geometry is optimized first to maximize the aerodynamic performance of the turbine [1].

How to Design Wind Turbine Blade Geometry for Optimal Aerodynamic Efficiency Engineering with Rosie 122000 subscribers 2388 likes 101573 views 10 Nov 2020 This is part 3 of my series: “How Does a Wind Turbine Work?” In this video I show you how to use the blade element momentum theory, BEM, that we discussed in the last videos, to design an efficient wind turbine rotor. Topics include: 00:33 Lift equation 00:47 Optimum aerodynamic conditions with constant circulation along the span 01:05 How the local wind speed and angle vary along the length of the blade 01:22 How to change the chord and twist angle along the blade span 01:50 Why designers normally modify the chord distribution to have smaller chords at the root 02:28 The torque equation and why the tip's aerodynamics is more important than the root 02:52 What happens if you use a turbine at a different wind speed than it was designed for 03:46 How variable speed turbines can operate efficiently over a wind range of wind speeds 04:18 What is tip speed ratio (TSR) and why is it important to wind turbine designers? 04:48 Blade solidity 06:07 How to find a starting point in the wind turbine blade design process 07:22 Why are wind turbine blades getting so skinny? 07:54 Reducing wind turbine noise by limiting rotational speed 08:29The different requirements of aerofoils at the root versus tip of the blade Check out part one and two of my “How Does a Wind Turbine Work?” series where I go through the mechanical engineering and aerodynamic theory needed to understand how a wind turbine works and design a wind turbine blade: How Much Energy is in the Wind? https://www.youtube.com/watch?v=7-awFXqisYA&t=7s How to Calculate Wind Turbine Power Output: Blade Element Momentum Method https://youtu.be/o6BCnhubbiQ If you want to follow the derivations I mentioned in this video then check out section 3.7.2 of Burton's "Wind Energy Handbook." Available to buy from Amazon (affiliate link), or your university library probably has it! https://amzn.to/32Pb1fh The optimum aerodynamic design equation at 6:10 has the following parameters: sigma_r = chord solidity at the radial location (chord length divided by swept circumference at that radial location) lambda = tip speed ratio (tip speed due to blade rotation (radial location times rotational speed) divided by wind speed) C_l = local lift coefficient mu = r/R (radial location divided by radius) 133 comments
