Mikro elektronik devrelerde metalik iletişim bağlarının elektro göç sonucu tahribatının bilgisayar modellemesi: Özellikle difüzyon anisotropisinin ve termal streslerin yüzey morfolojisine ve katot tahribatına etkileri

Computer simulation of grain boundary grooving and cathode voiding n bamboo interconnects by surface diffusion under capillary and electromigration forces Akyıldız, Öncü; Oğurtanı, Tarık Ö.; Department of Metallurgical and Materials Engineering (2004) The processes of grain boundary grooving and cathode voiding which are important in determining the life times of thin films connecting the transistors in an integrated circuit are investigated by introducing a new mathematical model, which flows from the fundamental postulates of irreversible thermodynamics, accounting for the effects of applied electric field and thermal stresses. The extensive computer studies on the triple junction displacement dynamics shows that it obeys the first order reaction kinet...
Experimental and numerical inestigation of an s-duct diffuser designed for a micro turbojet engine powered aircraft Aslan, Samet; Kurtuluş, Dilek Funda; Department of Aerospace Engineering (2016) S-duct diffusers are often used for aircraft propulsion systems that convey the intake air to the engine compressor. In this thesis, flow structure at separated entrance conditions in an S-duct diffuser that designed for a micro turbojet engine powered aircraft is investigated using experimental and numerical methods. Flow characteristics such as flow separation, secondary flows, and swirl are investigated to find out the source of distortions and pressure loss at aerodynamics interface plane. Experiments a...

Analytical solution for single phase microtube heat transfer including axial conduction and viscous dissipation Barışık, Murat; Güvenç Yazıcıoğlu, Almıla; Department of Mechanical Engineering (2008) Heat transfer of two-dimensional, hydrodynamically developed, thermally developing, single phase, laminar flow inside a microtube is studied analytically with constant wall temperature thermal boundary condition. The flow is assumed to be incompressible and thermo-physical properties of the fluid are assumed to be constant. Viscous dissipation and the axial conduction are included in the analysis. Rarefaction effect is imposed to the problem via velocity slip and temperature jump boundary conditions for the...
