Demonstration of a stabilized hovering platform for undergraduate laboratory
Çamlıca, Fahri Buğra; Erden, Abdülkadir; Department of Mechanical Engineering (2004)
This research work covers the design, manufacture and testing of an unmanned aerial vehicle for the purpose of testing various control systems by undergraduate students in the laboratory environment. The aerial vehicle under consideration is a four-rotor propeller powered. Aluminum rod based mechanical structure is preferred. The stabilization of the hovering vehicle in its rotational axes in the air and navigation about the yaw axis are the accomplished goals of this study. The aerial vehicle is run in rea...
Investigation of double-layered wavy microchannel heatsinks utilizing porous ribs with artificial neural networks
Bayer, Özgür; Baghaei Oskouei, Seyedmohsen; Aradag, Selin (2022-05-01)
© 2022 Elsevier LtdMicrochannel heatsinks with porous media, wavy and multi-layered configurations introduce compact designs and high efficiencies in cooling applications. Current Computational Fluid Dynamics (CFD) based study bridges the concept by introducing a novel double layered microchannel heatsink with wavy up-down and porous ribs alongside each other. Since Artificial Neural Network (ANN) trained by CFD results reveals designs with better thermal and hydraulic performance with an insignificant comp...
Theoretical and experimental investigation on characteristics of adsorption cooling systems using advanced porous materials
Bonyadi, Nima; Yamalı, Cemil; Baker, Derek Keıth; Department of Mechanical Engineering (2014)
The solid sorption cooling systems are getting more popular around the globe due to their benign behavior and possibility to work with renewable energy. Despite many advantages, the overall efficiency of adsorption cooling systems is still low in comparison to vapor compression chillers. Researchers declare that heat and mass transfer and adsorption capacity inside the adsorbent bed have dominant role on the performance of the cooling unit. One way to increase both adsorption capacity and heat distribution ...
Design of a secondary packaging robotic system
Şahin, Hakan; Balkan, Raif Tuna; Department of Mechanical Engineering (2005)
The use of robotic systems in consumer goods industry has increased over recent years. However, food industry has not taken to the robotics technology with the same desire as in other industries due to technical and commercial reasons. Difficulties in matching human speed and flexibility, variable nature of food products, high production volume rates, lack of appropriate end-effectors, high initial investment rate of the so-called systems and low margins in food products are still blocking the range of use ...
Theoretical and experimental investigation of ultrasound propagation in packed beds
Karakaş, Zeynep; Uludağ, Yusuf; Department of Chemical Engineering (2016)
Ultrasound propagation through porous medium is investigated theoretically and experimentally in this study. Allowing measurements with opaque medium, giving fast measurements, requiring low cost and being non-invasive make the use of ultrasound based techniques convenient. Propagation of sound is directly related to the physical properties of a porous medium such as porosity, bulk modulus of medium, density of medium, particle size and physical properties of sound such as frequency. Therefore, it becomes p...
