Effect of Wavy Trailing Edge on 100meter Flatback Wind Turbine Blade

Simulating Cooling Injection Effect of Trailing Edge of Gas Turbine Blade on Surface Mach Number Distribution of Blade

In this research, a gas turbine blade cascade was investigated. Flow analysis around the blade was conducted using RSM and RNG.K-ε turbulence modeling and it is simulated by Fluent software. The results were considered for the cases as Mach number loss at the trailing edge of blade caused by vortexes that were generated at the end of blade. Effect of cooling flow through the trailing edge on th...

Model Predictive Control of Trailing Edge Flaps on a Wind Turbine Blade

Trailing Edge Flaps on wind turbine blades have been studied in order to achieve fatigue load reduction on the turbine components. We show in this paper how Model Predictive Control can be used to do frequency weighted control of the trailing edge flaps in order to reduce fatigue damage on the blade root. The design model is based on a modal model of the blade structure and a steady state aerod...

Experiments Concerning the Effect of Trailing-Edge Thickness on Blade Loss and Turbine Stage Efficiency

Theoretical assessments of the influence of trailing-edge thickness on turbine blade loss coefficients are reviewed and compared with the results of a cascade tunnel investigation. Tests on a single-stage turbine indicate that efficiency is much more sensitive to stator blade trailing-edge thickness than simple estimates woul d indicate, but rotor blade thickness effects on efficiency are in li...

Aerodynamic Analysis of Trailing Edge Enlarged Wind Turbine Airfoils

Design of Wind Turbine Blade with Thick Airfoils and Flatback and its Aerodynamic Characteristic

large-scaled blade has posed many problems related to design and production. After introducing the features of blade with thick airfoils and flatback, based on relevant parameters of Huaren 100 kW wind turbine, the paper designed blade with thick airfoils and flatback, introduced blade parameter design, and analyzed the aerodynamic performance of blades using GH bladed software, obtaining the r...
