Effect of blade contamination on power production of wind turbines
Özgen, Serkan; Sarlbel, Eda Bahar; Yaman, Ali Rlza (2022-06-02)
© Published under licence by IOP Publishing Ltd.Wind turbines suffer from considerable power losses because of contamination on their blades, that can be due to erosion, wear, smog, insect, sand and dust particle impact. B...
Prediction of ice accretion shapes on aircraft wings using open-source software
Edeeb, Seghaer; Akay, Hasan U.; Özgen, Serkan (2021-10-01)
Ice accretion on aircraft components starts when an aircraft flies through atmospheric clouds containing supercooled liquid droplets, which have a temperature below freezing point but are still in a liquid state. Ice accre...
Improvement in the spring analogy mesh deformation method through the cell-center concept
Yang, Yosheph; Özgen, Serkan; Kim, Haedong (2021-08-01)
The mesh deformation method is an important topic in studies involving moving boundary problems. As one of the main approaches, this method has been applied in various related studies. To address the cell inversion problem...
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 condition...

Predictions of ice formations on wind turbine blades and power production losses due to icing
YIRTICI, ÖZCAN; Özgen, Serkan; Tuncer, İsmail Hakkı (Wiley, 2019-07-01)
Prediction of ice shapes on a wind turbine blade makes it possible to estimate the power production losses due to icing. Ice accretion on wind turbine blades is responsible for a significant increase in aerodynamic drag an...
Scaling for icing wind tunnel tests and validation with numerical simulations
Özbek Yanmaz, Gizem; Özgen, Serkan (null; 2019-07-01)
Objective of this study is to develop a scaling method that produces scaled ice accretions over a range of test conditions and to validate it for icing wind tunnel tests. A method for size and test-condition scaling that i...
Numerical simulation of ice accretion and consequent power loss estimation in wind turbine blades
Özgen, Serkan; Berker, Ayşe Meriç; Çakmak, Ali (null; 2019-07-01)
The aim of this study is to simulate atmospheric ice accretion on wind turbine blades and to estimate power losses. A computational tool is developed that comprises six modules, one for estimating the local flow velocity a...
