Triboelectric Turbines: Design And Construction Of A Multi-Rotor Counter-Rotating Wind Turbine Utilizing Direct-Current Triboelectric Nanogenerators, Adam Forti
Honors Theses
Direct-current triboelectric nanogenerators (DC-TENG) harness the friction generated between dissimilar rotating materials and convert it to useable electrical power. One of the many potential applications of this technology is in small scale renewable energy. A wind turbine was designed in which multiple DC-TENG generators would be attached to turbine blades of varying dimensions. This project involved the design and construction of several rotating DC-TENG prototypes, followed by measuring the electrical output of each nanogenerator at various rotational speeds.

Honors Theses
As the demand for wind power grows the technology used to research and further develop wind power must become more sophisticated. Experiments are expensive and require high end test facilities; a commonly used alternative to experimentation are computational fluid dynamic (CFD) models of wind turbines. For this project Star- CCM+ a CFD software was used to determine the power generated by small scale horizontal axis wind turbines. The Reynolds-Averaged Navier Stokes (RANS) equations were applied to the models in order to solve for the average flow. Though a variety of different types of simulations were used the focus was on …
