It is crucial to predict the ice mass, shape and regions of the airframe which are prone to icing in order to design and develop de/anti-icing systems for aircraft and airworthiness certification . In the current study, droplet collection efficiency and ice shape predictions are performed using an originally developed computational tool for a wing tip for which experimental and numerical data are available. Ice accretion modeling consists of four steps in the developed computational tool: flow field solution, droplet trajectory and collection efficiency calculations, thermodynamic analyses and ice growth calculations using the Extended Messinger Model. The models used for these steps are implemented in a FORTRAN code, which is used to analyze ice accretion on 2D geometries including airfoils and axisymmetric inlets. The results are compared with numerical and experimental data available in the literature.

In-flight Ice formation simulation on finite wings and air intakes
Özgen, Serkan (2012-04-01)
In the present article, in-flight ice formation on finite wings and air intakes of low-speed aircraft are numerically studied. The approach to the problem involves calculation of the velocity field using a three-dimensional panel method. Using the calculated velocity field, the droplet trajectories and droplet impact locations are computed yielding the droplet collection efficiency distribution. In the next step, convective heat transfer coefficient distributions around the geometries are calculated using a...
A new method to determine dynamically equivalent finite element models of aircraft structures from modal test data
Karaağaçlı, Taylan; Yıldız, Erdinç N.; Özgüven, Hasan Nevzat (Elsevier BV, 2012-8)
Flutter analysis is a major requirement to predict safe flight envelops and to decide on flutter testing conditions of newly designed or modified aircraft structures. In order to achieve reliable flutter analysis of an aircraft structure, it is necessary to obtain a good correlation between its finite element (FE) model and experimental modal data. Currently available model updating methods require construction of a detailed initial FE model in order to achieve convergence of the modes obtained from updated...
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 accretion occurs when water droplets impinge and freeze on the unprotected frontal regions of aircraft surfaces. The accumulated ice on aircraft components degrades the aircraft performance and causes serious flight problems. In this study, a computational fluid dynamics package is developed us...
Ice accretion simulation on finite wings with extended Messinger Method
Özgen, Serkan (2008-05-23)
Numerical icing simulations on finite wings are performed using a quasi-3D approach. The solution method consists of computations of the flowfield using the Hess-Smith panel method, droplet trajectories, droplet collection efficiencies, convective heat transfer coefficients and finally ice accretion rates and ice shapes. Inputs to the problem are the ambient temperature T(a), freestream velocity V(infinity), liquid water content of air rho(a) droplet diameter d(p), total icing time t(exp), angle of attack a...
