In the present study, the aim is to predict ice accumulation on a 2-D commercial engine intake. The developed tool mainly consists of four modules: modules for the calculation of the flow-field, droplet trajectories and collection efficiencies, thermodynamics and ice accretion. The flow-field solution is done by a panel method modified for the intake geometry and the required engine mass flow rate using a superposition technique. The droplet trajectories are computed using the Lagrangian approach, while the Extended Messinger Model is implemented in the ice accretion module. The results are compared with numerical literature data.

Icing on wind turbine blade under various atmospheric conditions
Yırtıcı, Özcan; Özgen, Serkan; Tuncer, İsmail Hakkı (2017-09-30)
It is important to predict the ice shape with amount of accreted mass on the surface of turbine blade in order to design and develop de/anti-icing systems for wind turbines located in cold climate regions. Ice accretion on the blades change the initial shape and this cause alteration in the aerodynamic characteristic of the blades. To this end, icing module combined with the BEM method to predict the shape of the iced blade sections of the turbine blade under atmospheric icing conditions. The obtained resul...
Ice accretion simulation on multi-element airfoils using extended Messinger model
Özgen, Serkan (Springer Science and Business Media LLC, 2009-01-01)
In the current article, the problem of in-flight ice accumulation on multi-element airfoils is studied numerically. The analysis starts with flow field computation using the Hess-Smith panel method. The second step is the calculation of droplet trajectories and droplet collection efficiencies. In the next step, convective heat transfer coefficient distributions around the airfoil elements are calculated using the Integral Boundary-Layer Method. The formulation accounts for the surface roughness due to ice a...
Vehicle wind noise prediction through solutions of Navier-Stokes and Ffowcs Williams Hawkings equations
Gümüş, Baran; Güneş, Ezgi; Özyörük, Yusuf (2017-09-20)
The aim of this study is to calculate flow noise of a car model at a far field location. Aeroacoustic calculations for non-reduced models require excessive computing source. Ffowcs Williams and Hawkings (FWH) method is one of the most effective methods of Computational Aero Acoustics (CAA) in terms of computational cost. The FWH method is a hybrid method, which consists of a near field flow solution and then a linear acoustic propagation to far field. Acoustic sources around the vehicle must be captured acc...
Sensorless vector control of induction motor based on flux and speed estimation
Ertuğrul, Barış Tuğrul; Ersak, Aydın; Department of Electrical and Electronics Engineering (2008)
The main focus of the study is the implementation of techniques regarding flux estimation and rotor speed estimation by the use of sensorless closed-loop observers. Within this framework, the information about the mathematical representation of the induction motor, pulse width modulation technique and flux oriented vector control techniques together with speed adaptive flux estimation a kind of sensorless closed loop estimation technique- and Kalman filters is given. With the comparison of sensorless closed...
Heat Distribution within the Wellbore While Drilling
Apak, E. C.; Ozbayoglu, E. M. (Informa UK Limited, 2009-01-01)
Analysis of the drilling fluid temperature in a circulating well is the main objective of this study. Initially, different analytical temperature distribution models were studied. Variables that have significant effect on temperature profile are observed. Since the verification of the analytical model is not probable for many cases, a computer program that uses a finite element method is employed to simulate different well conditions. Three different wells are modeled by using rectangular elements with four...
