A quasi-one-dimensional bubbly cavitating flow model and comparison with experiments
(European Turbomachinery Soc-Euroturbo, 2011)
A bubbly cavitating flow model is constructed for unsteady quasi-one-dimensional and two-dimensional nozzle flows. In each case, the system of model equations is reduced to evolution equations for the flow velocity and ...
Effects of turn-milling conditions on chip formation and surface finish
(Elsevier Science BV, 2019-04-24)
Turn-milling operations performed on mill-turn machines offer significant advantages provided that appropriate conditions are used. Compared to conventional machining processes, kinematics and geometry of turn-milling are ...
Numerical investigation of the effect of radial lip seal geometry on sealing performance
(IOP Publishing Ltd, 2018)
Sealing elements are often needed in industry and especially in machine design. With the change and development of machine technology from day to day, sealing elements show continuous development and change in parallel ...
A flexible adaptive optics concept for general purpose high angular resolution science on the DAG 4m telescope
(SPIE-Int Soc Optical Engineering, 2018)
Thanks to the availability of high actuator density deformable mirrors (ALPAO 468 DM), the high versatility of the pyramid wavefront sensor and above all, the venue of essentially no noise EMCCD detectors, it becomes ...
Frezeyle tornalamada takımda ortaya çıkan termal deformasyonların modellenmesi
(Gazi Universitesi Muhendislik-Mimarlik, 2017)
Frezeyle tornalama işleminde işlemiş parça doğruluğu ve üretkenliği arttırarak işlem performansını iyileştirmek kesme kuvvetlerini ve takım ucundaki ısı kaynaklı deformasyonları kontrol etmekle mümkündür. Bu çalışmanın ...
A refinement of asymptotic predictions and full numerical solution of helicopter rotor noise in the far field
(Multi-Science Publ Co Ltd, 2012-09-01)
The asymptotic analysis of Parry and Crighton [1] for propeller noise in the far field, which is based on Hanson's formulation [2] of the FW-H equation, is refined to second order by Laplace's method [3] for evaluating ...
Mechanical and thermal modeling of orthogonal turn-milling operation
(Elsevier Science BV, 2017)
Turn-milling is a relatively new machining technology which is performed for cutting of symmetrical or non-symmetrical rotational parts. To improve productivity, determination of cutting parameters in turn-milling is ...
In Flange Derotator Design for the 4m DAG telescope
(SPIE-INT Soc Optical Engineering, 2018-07-06)
The field rotation effect can be described as observing the gyration of an object with the pupil of the Eastern Anatolian Observatory (DAG) telescope around the optical axis under the influence of the latitude of the ...
Extremum seeking control of uncertain systems
(Işık University Press, 2017)
Extremum seeking is used in control problems where the reference trajectory or reference set point of the system is not known but it is searched in real time in order to maximize or minimize a performance function representing ...
A global optimal control methodology and its application to a mobile robot model
(Elsevier B.V., 2016)
A global optimal control algorithm is developed and applied to an omni-directional mobile robot model. The aim is to search and find the most intense signal source among other signal sources in the operation region of the ...
