Effects of Active and Passive Control Techniques on Mach 1.5 Cavity Flow Dynamics 

Aradağ, Selin; Gelisli, Kubra Asena; Yaldir, Elcin Ceren (Hindawi Ltd, 2017)
Supersonic flow over cavities has been of interest since 1960s because cavities represent the bomb bays of aircraft. The flow is transient, turbulent, and complicated. Pressure fluctuations inside the cavity can impede ...

Artificial Neural Network Based Prediction Of Time-Dependent Behavior For Lid-Driven Cavity Flows 

Paksoy, Akın; Aradağ, Selin (Turkish Soc Thermal Sciences Technology, 2015)
In this study, computational fluid dynamics (CFD) analyses of the two-dimensional, time-dependent lid-driven cavity flows, for Reynolds numbers ranging from 100 to 10000, are performed by using an in-house developed CFD ...
Thumbnail

Comparative gasketed plate heat exchanger performance prediction with computations, experiments, correlations and artificial neural network estimations 

Aradağ, Selin; Genc, Yasin; Turk, Caner (Hong Kong Polytechnic Univ, Dept Civil & Structural Eng, 2017-04-27)
Gasketed plate heat exchangers (GPHEX) are popular due to their small volume, ease of cleaning and high thermal performance. Hydraulic and thermal performance of GPHEX are not as easily determined since they solely depend ...

Numerical research of cavitation on Francis turbine runners 

Celebioglu, Kutay; Altintas, Burak; Aradağ, Selin; Taşcıoğlu, Yiğit (Pergamon-Elsevier Science Ltd, 2017-07-13)
Francis turbines, as other hydraulic turbines, are custom-designed for nominal operating conditions specific to each power plant. However, they may need to be operated at off design flow conditions because of variable ...
