ICE ACCRETION PREDICTION ON HORIZONTAL AXIS WIND TURBINE BLADES
Yırtıcı, Özcan; Özgen, Serkan; Tuncer, İsmail Hakkı (null; 2015-09-10)
Ice accretion on the blades change the initial shape and this cause alteration in the aerodynamic characteristic of the blades. The objective of this study is to predict the shape of the iced blade sections of the turbine blade under atmospheric icing conditions. The obtained results are verified with experimental and numerical ice shapes reported in the literature. In all the cases studied, the current numerical tool yields results that are in fair agreement with the compared results and can be used to pre...
Ice Accretion Prediction on Wind Turbines and Consequent Power Losses
YIRTICI, ÖZCAN; Tuncer, İsmail Hakkı; Özgen, Serkan (2016-10-07)
Ice accretion on wind turbine blades modifies the sectional profiles and causes alteration in the aerodynamic characteristic of the blades. The objective of this study is to determine performance losses on wind turbines due to the formation of ice in cold climate regions and mountainous areas where wind energy resources are found. In this study, the Blade Element Momentum method is employed together with an ice accretion prediction tool in order to estimate the ice build-up on wind turbine blades and the en...
Ice accretion prediction with mixed phase cloud particles
Ayan, Erdem; Özgen, Serkan; Department of Aerospace Engineering (2017)
Existence of ice crystals in convective clouds has become one of the major threats for flight safety. Several flight incidents have been reported in the last decades due to ice accretion around heated surfaces like air probes or on engine components. Ice accretion due to water droplets is a well studied issue. However, ice accretion due to ice particles is a relatively new aspect and the physics are not yet fully understood. Hence adequate models for representing the physical phenomena are very scarce. Within...
Ice Accretion Prediction on Engine Nacelles in Liquid Phase Clouds
Özgen, Serkan; Görgülü, İlhan; Tatar, Volkan (null; 2015-09-22)
More than a hundred in-flight incidences have been reported in the last two decades related to icing on aircraft engine components including rollbacks, mechanical failure and flameouts [1, 2]. Thus, in-flight ice accretion on aircraft engine components and nacelles has been attracting more interest, especially from the airworthiness certification point of view. Computer simulations as well as ground and flight tests are among the means of compliance for airworthiness certification related to safe flight in ...
