Ice formation on a wind turbine alters the airfoil profiles of the blades and causes degradation in the aerodynamic performance of the wind turbine and the resulting power production losses. Since the blade profile plays a significant role in the icing of a blade, power production losses due to icing can be minimized by optimizing the blade profile against icing. In this study, blade profiles are optimized in order to minimize power production losses. A Gradient based aerodynamic shape optimization method is developed together with the Blade Element Momentum method and an ice accretion prediction tool in order to minimize the power production losses of horizontal axis wind turbines under various icing conditions. In an optimization study performed for the AeolosH 30 kW and NREL 5 MW wind turbines exposed to icing conditions up to 1 h, the power loss due to icing is reduced by about 4%.

Aerodynamic Shape Optimization for Reducing Ice Induced Losses on Wind Turbine Blades Yırtıcı, Özcan; Tuncer, İsmail Hakkı (null; 2019-05-14) Ice accretion on wind turbines modifies the blade shape profile and causes alteration in the aerodynamic characteristics of the blades. The objective of this study is to optimize the blade geometry to reduce performance losses by minimizing ice accretion in cold climate regions and mountainous areas where wind energy resources are plentifully found. In this study, The Gradient Based Optimization Method and Blade Element Momentum Method will be employed together with an ice accretion prediction tool for esti...
Genetic algorithm based aerodynamic shape optimization of wind turbine rotor blades using a 2-d panel method with a boundary layer solver Polat, Özge; Tuncer, İsmail Hakkı; Sezer Uzol, Nilay; Department of Aerospace Engineering (2011) This thesis presents an aerodynamic shape optimization methodology for rotor blades of horizontal axis wind turbines. Genetic Algorithm and Blade Element Momentum Theory are implemented in order to find maximum power production at a specific wind speed, rotor speed and rotor diameter. The potential flow solver, XFOIL, provides viscous aerodynamic data of the airfoils. Optimization variables are selected as the sectional chord length, the sectional twist and the blade profiles at root, mid and tip regions of...
DESIGN OF HELICOPTER TRANSMISSION OIL COOLING FAN IMPELLER WITH MULTI-OBJECTIVE OPTIMIZATION METHOD Avşar, Gökhan; Başkan Perçin, Özge; Department of Aerospace Engineering (2023-1-18) This study aims to optimize the impeller geometry of a backward-curved blade centrifugal fan in a helicopter oil cooler to improve the aerodynamic performance of the impeller. The study consists of three main parts: aerodynamic design and parametrization of the impeller, numerical analysis of impeller performance, and multi-objective design optimization to maximize fan static pressure and total to static isentropic efficiency. In the first part, a one-dimensional impeller design is performed using quasi-exp...
Experimental Study of a TLP Offshore Floating Wind Turbine Oğuz, Elif; Clelland, David; İncecik, Atilla; Dai, Saishuai; López, Juan Amate; Sánchez, Gustavo (null; 2016-07-18) Tank testing in a wind and wave environment is a key part of the design process for the development of an offshore floating wind turbine. The current paper describes an extensive experiment campaign carried out at the Kelvin Hydrodynamics Laboratory at the University of Strathclyde to determine the hydrodynamic performance of the Iberdrola TLPWIND offshore floating wind turbine with the NREL 5MW reference turbine over a range of environmental conditions. Tests were carried out for 70m water depth and the de...
Aerodynamic validation studies on the performance analysis of iced wind turbine blades YIRTICI, ÖZCAN; Cengiz, Kenan; Özgen, Serkan; Tuncer, İsmail Hakkı (Elsevier BV, 2019-10-15) Ice accretion on wind turbine blades distorts blade profiles and causes degradation in the aerodynamic characteristic of the blades. In this study ice accretion on turbine blades are simulated under various icing conditions, and the resulting power losses are estimated. The Blade Element Momentum method is employed together with an ice accretion prediction methodology based on the Extended Messinger model in a parallel computing environment. The predicted iced profiles are first validated with the experimen...
