The Mechanical Engineering department post graduate presentations were held on the 7th June 2016 where a total of five presentations were made. Members of staff and students in the department were in attendance to offer the much needed support in terms of suggestions and ideas.
The first presentation was on the “Characterization of Fatigue Properties of Secondary Cast Aluminium Silicon Alloys for Cylinder Head Applications” by Gaudence Nyarirazena.The main objective of her research is to study fatigue properties of recycled Al-Si.
The second presentation was on “Performance Optimization of a Thermosyphon Flat Plate Solar Water Heater” by John Ng’ethe. He has fabricated a flat plate solar water heater with serrations that are 60o to reduce the thermal losses that occur through radiation, conduction and convection.
The third presentation was on the “Failure Analysis on Conveyor Chain Links of a Central Bucket Elevator” by Edward Yin. His analysis looks at the causes of chain failure
The fourth Presentation was on “Linear Wear Reduction in a Single- Toggle Jaw Crushers” by Gideon Quartey. He approached the problem of linear wear on Jaw crusher used in the mining industry through a proposing a change of design and he has simulated his design using FEA Ansys.
The final presentation was on “Optimization of a Compression Ignition Engine Running on Croton Esters-Diesel Blends” by Obadiah Maswai. He tested various blending ratios of the croton ester and diesel and he concluded that the optimum blending ratio is 10-20%.
