Triboelectric Solar Generator Concept And Experimental Research, Elias Yazdanshenas
Mechanical & Aerospace Engineering Theses & Dissertations
In this thesis, a novel concept, a triboelectric solar generator (TSG ), is proposed for generation of high voltage direct current (HVDC) electricity from solar radiation. An experimental investigation was conducted to prove the concepts of charge generation through the triboelectric effect and charge transmission using semiconductors. The triboelectric effect, also known as the contact electrification, is a well-known physical phenomenon that electrostatic charges are generated by rubbing dissimilar materials. However, traditional triboelectric generators had never been commercialized due to their poor power output. Physically, it is due to the difficulty of charge transmission from insulators, which generate charges. The …

Fixture Design For Load Measurement In Friction Stir Welding, Shekhar S. Kulkarni
Mechanical & Aerospace Engineering Theses & Dissertations
In the Friction Stir Welding Process a vertical force is required for plunging the pin or probe of the tool into the workpiece specimen material, and maintaining contact between the shoulder and the substrate. In addition to the vertical force, Friction Stir Welding Process also involves a horizontal force, which is instrumental for the advancement of the tool as the weld progresses. The essential objective of the thesis was to design, manufacture and test a fixture that can be utilized to measure the vertical force as well as the horizontal force. The designing of the fixture was concerned with various …
