Makina mühendisliğinin uygulamalarında fan ile pompalar önemli bir yer oluşturmaktadır. Günümüzde kullanılan fan ve pompaların performanslarına ek olarak bu cihazların aero-akustik özellikleri ve dışarıya yaydıkları gürültü düzeyleri önemli bir problem olarak ortaya çıkmaktadır. Ses düzeyini istenilen seviyelerde tutacak tasarımlar yapabilmeye yönelik bilgi birikimi akışkanlar mekaniği, turbomakinalar, akustik ve mekanik titreşim konuları ile tasarım metodolojilerini biraraya getiren karmaşık bir araştırma konusu olmaktadır. Bu konuda çeşitli standardlar geliştirilmiş olup, analitik tahmin metodları ve ölçüm düzenekleri konusunda çalışmalar devam etmektedir. Proje kapsamında aksiyel ve santrifüj pompa ve fanların gürültü seviyeleri ve akustik özellikleri belirlenmiştir. Çalışma dahilinde Ortadoğu Teknik Üniversitesi Makina Mühendisliği Bölümü Akışkanlar Mekaniği Laboratuarında endüstri desteğiyle bu çalışmaya yönelik olarak yapılmış olan yarı-çınlamalı (semi-anechoic) oda kullanılacaktır. Çalışma üç temel aşamadan oluşmaktadır. İlk aşamada inşa edilen odanın uluslar arası standardlara uygunluğu belirlenecek, ikinci aşamada santrifüj fanların akışkandan (hava) kaynaklanan gürültü ve ses özellikleri belirlenecektir. 3. aşamada gene santrifüj pompaların akışkandan (su) kaynaklanan akustik özellikleri ve gürültü düzeyleri belirlenecektir. Çalışma sonunda akışkan etkisiyle oluşan ses ve gürültü düzeyleri ve buna bağlı bir tahmin metodu belirlenecektir. Projeye kapsamında yapılacak çalışmalar, bir doktora çalışması ile 2 yüksek lisans çalışmasını içermektedir.

Design optimization of truss structures using genetic algorithms Ünalmış, Dilek; Kayran, Altan; Department of Aerospace Engineering (2012) Design optimization of truss structures is a popular topic in aerospace, mechanical, civil, and structural engineering due to benefits to industry. Common design problem for the structures is the weight minimization. Especially in aerospace engineering the minimization of the weight of the total structure gets the highest importance in the design. This study focuses on the design optimization of 2D and 3D truss structures. The objective function is the total mass of the structure which is subjected to stres...
Multi-support seismic excitation of long span highway bridges Gökdemir, Tunç; Askan Gündoğan, Ayşegül; Caner, Alp; Department of Civil Engineering (2017) Seismic design and analysis are common practices in bridge engineering which require both knowledge and experience. Technical standards, such as CALTRANS (2010) and AASHTO (2007) provide guidance on the analysis with the methods ranging from Response Spectrum Analysis (RSA) to Time History Analysis (THA). These methods are usually sufficient for obtaining the seismic behavior of common structures and capture the dynamic behavior with decent accuracy. However, this may not be the case for structures which sp...
Momentum exchange in coaxial jet flows Peker, Ekim Atilla; Aydın, İsmail; Department of Civil Engineering (2005) Coaxial jet flows have a considerable practical application area as water jet pumps. Efficiency of such systems is affected by complex turbulence mechanisms and large-scale vortex structures formed in the mixing regions. An experimental setup is constructed to estimate the momentum exchange rates and mixing of the two jet flows from the coaxial pipes. Pressure distributions along the mixing pipe wall are measured for different flow ratios of the jets. In addition to present experiments, numerical data of tw...
Utilization of friction stir processing to improve the mechanical properties of gas metal arc welded 5083 aluminum alloy plates Takht Firouzeh, Shahin; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2016) Fatigue failure of the welded structures is a major problem in engineering applications. It is known that the heat affected zone (HAZ) of the welded Al-alloys is prone to fail due to coarse microstructure and poor mechanical properties. Therefore, any improvement in HAZ may extend the service life of the welded component. The hypothesis of this study is that localized application of friction stir processing (FSP) before welding may improve the mechanical properties of HAZ, and thus, may reduce the fatigue c...
Adsorption of aromatic molecules on rutile TiO2(110) surfaces Mesta, Murat; Ellialtıoğlu, Süleyman Şinasi; Department of Physics (2009) Transition metal oxides having high dielectric constants and wide band gaps find very important and interesting technological applications in surface physics. In particular, titania is the most commonly used material in heterogeneous catalysis because of its stable and flat surfaces. Having Ti cations at different charge states within the system brings about various novel electronic properties which are mainly surface related. Adsorption of catalytically important or chemically useful molecules on titania s...
