Manufacturing Engineering
(2003)
Opened in 2003 with the aim to graduate experts in the field of machine-production, our Department is among the firsts in our country to offer education in English. The Manufacturing Engineering program focuses on the manufacturing technologies that shape materials from raw materials to final products by means of analytical, experimental and numerical modeling methods. First Manufacturing Engineering Program to be engineered by Müdek, our department aims to graduate creative and innovative Manufacturing Engineers that are knowledgeable in the current technology, and are able to use production resources in an effective and sustainable way that never disregards environmental facts. As the first Department to implement the Cooperative Education Program at Atılım University in coordination with institutions from the industry, the Manufacturing Engineering offers a practice-oriented approach in education with its laboratory infrastructure and research opportunities. The curriculum at our department is supported by current engineering software, and catered to creating engineers equipped to meet the needs of the production industry.

The Atılım University Department of Computer Engineering was founded in 1998. The department curriculum is prepared in a way that meets the demands for knowledge and skills after graduation, and is subject to periodical reviews and updates in line with international standards. Our Department offers education in many fields of expertise, such as software development, hardware systems, data structures, computer networks, artificial intelligence, machine learning, image processing, natural language processing, object based design, information security, and cloud computing. The education offered by our department is based on practical approaches, with modern laboratories, projects and internship programs. The undergraduate program at our department was accredited in 2014 by the Association of Evaluation and Accreditation of Engineering Programs (MÜDEK) and was granted the label EUR-ACE, valid through Europe. In addition to the undergraduate program, our department offers thesis or non-thesis graduate degree programs (MS).

Abstract

Bu çalışmada mikroakışkan uygulamalarındaki kıvamlı yavaş akışta birden çok parçacığı izlemek için yeni bir formülasyon sunulmaktadır. Yöntem, sınır eleman matrislerinin manipülasyonu işlemininden sonra, parçacığın katı bünye hızları ile üzerine etki eden kuvvetleri ilişkilendiren bir denklem sistemi elde etmektedir. Formülasyon, SMP paralelleştirme yönteminin uygulandığı ardışık matris çarpımı işlemleri sonucunda özellikle parçacığın yörüngesinin takibi için tasarlanmıştır. Mevcut formülasyon, parçacık izleme işlemi için kullanılmak üzere etkili bir sayısal model sunmaktadır ve kolay bir şekilde birden çok fiziksel etkinin içerildiği çoklu-fizik simülasyonları için genişletilebilir olduğu görülmektedir.
A new formulation for tracking multiple particles in slow viscous flow for microfluidic applications is presented. The method employs the manipulation of the boundary element matrices so that a system of equations is obtained relating to the rigid body velocities of the particle to the forces applied on the particle. The formulation is specially designed for particle trajectory tracking and involves successive matrix multiplications for which Symmetric Multiprocessing (SMP) parallelisation is applied. It is observed that the present formulation offers an efficient numerical model to be used for particle tracking and can easily be extended for multiphysics simulations in which several physics are involved.
