ME 407 PROJECT ALTERNATIVES FOR 2016-2017 ACADEMIC YEAR

1. Design of a Test Setup that can measure frictional torque of different kinds of bearings under controlled parameters – Sponsored by ORS. (T. Akyürek)

A new test system that will measure frictional torque of different type bearings under controlled axial and radial loads, temperature, rotational speed and vibration conditions will be designed. The bearings will be tested  at -40/200 C temperature range. Rotational speed is to be controlled upto 15000 rpm.


2. Design and Test of a Rotational Viscometer (H. Türkoğlu)

In this project, a rotational type viscometer will be designed and manufactured to use for viscosity measurement of Newtonian fluids.  The device is based on the measurement of torque required to rotate a cylindrical surface in a liquid. Utilizing the Newton’s law of viscosity, viscosity of the liquid will be determined from the measured torque. The main parts of the device consist of a stationary cylindrical vessel, a rotating cylinder, a mechanism to measure the torque and a simple microprocessor to control the device and relate the measured torque to viscosity of fluid.


3. Innovative Gate Design for Physical Security – Sponsored by OPTIMA Security Systems.

A new gate physical security system that will not allow passage of any foreign car through the gate will be designed. The gate will provide a protection under even intentional collision at a high speed. Simulation of the crash test will be delighter by the company.


4. Computer Controlled Material Mixing System Design – Sponsored by NA-ME.

Composite resin and other binding material at the desired quantity will be brought together, mixed, transferred to the mould that has the continuous fibers laid in a open mould, heated and cooled for curing process. Quantity control of the powder material at the desired precision is the crucial point. Control of moveable parts pneumatically rather than electrically is preferred. A confidentiality agreement is to be signed at the beginning of the project.


5. Rolling Machine Design for Metal Bending – Sponsored by Cematek Metalworking Machinery.

A rolling machine that will bent metalic strips to the straight form and bent into desired profile will be designed. Bending will be at high speed. The strip that is bent to desired profile will be cut at the desired length. Roller positions should be easily adjusted for different size and form strips. Strips are in coil form.


6. Design of a Syringe Pump with Temperature Control for Microfluidic Systems. (E. Yıldırım)

Syringe pump is a device operated by pushing or pulling the piston of a standard medical syringes at constant speed to provide injection or retraction of the liquid in the syringe at a constant flow rate. These devices are often used in testing and operating microfluidic devices. Syringe pumps designed specifically for microfluidic devices can provide flow rates ranging roughly between 0.1 – 1000 µl/min. In some cases, it is also required to keep the temperature of the liquid constant. In this project, the students are expected to design and implement a syringe pump with temperature control for using with microfluidic systems.


7. Design of a Contact Angle Goniometer to Determine Contact Angle of Various Liquids on Solid Substrates. (E. Yıldırım)

Contact angle goniometer is mainly an optical device which is used to measure static, advancing and receding contact angles of liquids on solid substrates. The device, basically takes the snapshot of a droplet of liquid on a substrate and the angle between the droplet and the solid surface is determined through image processing. Cameras for taking the snapshot of the droplet are commercially available. Similarly, there are readily available open source software for processing the snapshot of the droplet. The students are expected to design and implement the mechanical frame, which should robustly align the camera, droplet, the dispenser to inject the droplet, and the solid substrate, and the liquid dispenser, which should be capable of injecting the liquid at a few nl/min rate on the solid substrate. Students are also expected to integrate these with the camera and the image processing software.


8. Design and performance analysis of a solar parabolic trough collector with a tracking mechanism. (E. Özgirgin)

Parabolic trough collectors are concentrating collectors which reflect the solar rays to a single tube through which the working fluid (water) is circulated and heated. They can achieve higher temperatures than a flat-plate system. Solar energy is optically concentrated before being transferred into heat in a parabolic trough system. With a tracking mechanism which follow the sun with a certain degree of accuracy, parabolic trough collectors become one of the most  advanced solar thermal technology. The project covers thermal and optical design of the collector with respect to specifications, mechanical design of the tracking mechanism and all relevant tests and analysis of the solar system.


9. Design and performance analysis of an evacuated tube solar collector using different nanofluids as working fluid. (E. Özgirgin)

Evacuated tube solar collectors are composed of multiple evacuated glass tubes each containing an absorber plate fused to a heat pipe. They operate like flat-plate collectors, collecting both direct and diffuse radiation but  their efficiency is higher in terms of daylong performance. The thermal performance of  Evacuated tube solar collectors are significantly affected by structure and geometry, concentration of solar radiations, inclination angle and most importantly thermophysical properties of working fluid which can directly determine whether the collector is effective in the operation. The project covers thermal design of the collector considering structure and geometry with respect to specifications, Analysis of different working fluids and comparison with respect to thermal performance of the collector and all relevant tests and analysis of the solar system.
