The Effects of Static Aeroelasticity on the Performance of Supersonic/Hypersonic Nozzles

The Effects of static aeroelasticity on the performance of two-dimensional converging diverging nozzles Düzel, Ümran; Eyi, Sinan; Department of Aerospace Engineering (2014) This thesis analyzes the effects of static aeroelasticity on the performance of two dimensional converging diverging nozzles. A Flow analysis is conducted on five different configurations of two dimensional converging-diverging nozzles. Computational study is validated with experimental data. Two of the configurations, which have the same throat area, throat radius, and convergence angle and total nozzle length, are selected as the baseline geometries. By modifying throat radius and keeping all other geomet...

The effects of post-annealing process on the physical properties of silver-indium-selenium ternary semiconductor thin films deposited by electron beam technique Çolakoğlu, Tahir; Parlak, Mehmet; Department of Physics (2009) Ternary chalcopyrite compounds are the semiconductors with suitable properties to be used as absorber materials in thin film solar cells. AgInSe2 is a promising candidate with its several advantages over the widely used CuInSe2. The purpose of this study was to optimize the physical properties of the Ag-In-Se (AIS) thin films that were deposited by e-beam evaporation of Ag3In5Se9 single crystal powder for solar cell applications by means of post-annealing process under nitrogen atmosphere. The as-grown AIS ...
The Effect of dispersed phase feed rate on the production of pickering emulsions Dönmez, Dila; Ayrancı Tansık, İnci; Department of Chemical Engineering (2018) Emulsions are fundamental in many applications such as food, petroleum, detergent, pharmaceutical and cosmetic industries. Pickering emulsions are defined as emulsions of any type, either oil-in water, water-in-oil or even multiple, stabilized by solid particles instead of surfactants. Solid particles may prevent the droplets from coalescing by getting adsorbed at the interface, and thus stabilizing the emulsion. Pickering emulsions have more advantages over emulsions stabilized by surfactants in terms of s...
