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 is based on similitudes of geometry, flow field, droplet trajectory, water catch, energy balance and surface water dynamics is validated using ANSYS® Fluent 18.0 CFD tool and icing code FENSAP-ICE. The ice shapes obtained are verified with experimental data and the scaling method is tested ...
Scaling for icing wind tunnel tests andvalidation with numerical simulations
Özbek Yanmaz, Gizem.; Özgen, Serkan; Department of Aerospace Engineering (2019)
Icing is one of the most dangerous hazards to be encountered by air vehicles in flight. Ice accretion, particularly on control surfaces, wings and flight data sensors usually degrades both performance and operational safety of air vehicles. Thus, it has become important in the design and certification phases of system development to evaluate performance degradation because of icing. Icing wind tunnel testing is the most convenient method considering feasibility, cost and safety. However, when full-size mode...
Scaling and Selection of Ground Motion Records for Nonlinear Response History Analysis of Structures
Ay, Bekir Özer (2012-09-28)
Accurate estimation of structural response for a given target hazard level requires a suitable set of ground-motion records that represents a pre-defined scenario event. With the aim of assessing the seismic performance of structural systems, this study presents a ground motion selection and scaling methodology. Given a relatively larger ground-motion database, the method uses the differences between individual records and corresponding estimations of a ground-motion prediction equation in order to determin...
Prediction models for discharge estimation in rectangular compound broad-crested weirs
Al-Khatib, Issam A.; Göğüş, Mustafa (2014-04-01)
Experimental results of the flow of water over 9 different rectangular compound broad-crested weirs with varying lower weir crest width and step height were analyzed to develop prediction models for discharge estimation. The compound cross sections were formed by a combination of three sets of step heights and three sets of lower weir crest widths in a horizontal laboratory flume of 11.0 m length, 0.29 m width and 0.70 m depth. Flow depths at the approach channels were measured for a wide range of discharge...
Modeling guided heat pipe design methodology and experimental validation for flat grooved heat pipes
Saygan, Samet; Dursunkaya, Zafer; Çetin, Barbaros; Department of Mechanical Engineering (2021-2-24)
Heat pipes are commonly preferred thermal management devices due to their rapid heat transfer characteristics, small size and reliability. It is crucial to design heat pipes that accurately match the requirements of the system to be thermally managed. In the present study, a numerical design and diagnosis simulation tool for heat pipes is developed and verified for grooved heat pipes. A modular heat pipe experimental setup is designed and manufactured. In order to decide on the geometric parameters of the h...
