TOPIC:
A Comparison of Viscous Models for Computational Fluid Mechanics
ABSTRACT:
Computational Fluid Dynamics (CFD) is an extremely powerful tool for assessing complex systems or those that aren't well documented, however it is far from being able to process complex systems in real time. Naval Undersea Warfare Center (NUWC) Division Newport's Underwater Vehicle Launch Dynamics Simulation (UVLDS) code is considered the Navy's gold standard for real time launch trajectory analysis of devices. To aid in better tuning input files for the UVLDS, transient CFD simulations are being performed to improve the understanding of the forces and moments that arise in certain fringe cases. As part of this investigation, extensive research has been performed on the viscous solvers used by ANSYS Fluent. This presentation focuses on the k-ϵ and k-ω 2 equation viscous models, their advantages, disadvantages, and some of the common corrections used for them.

TOPIC:
Energy Harvesting of Flow-Induced Vibrations Using Sliding-Mode Triboelectric Nanogenerators
ABSTRACT:
Energy harvesting of mechanical systems has taken many forms such as piezoelectric, electrostatic, and electromagnetic transduction. Introduced in 2012, Triboelectric Nanogenerators have begun to be integrated into fabrics, jewelry, and microsensors. Typical Triboelectric Nanogenerators rely on contact electrification on which certain materials are electrically charged once they separate from each other or come into contact with a different material. While studies of Triboelectric materials have been thorough, its integration onto specific applications has been lacking. One such application is to use Sliding-Mode Triboelectric Nanogenerator (S-TENG) to harvest electrical energy from fluid flow. S-TENGs could be integrated into already existing wave energy converters to harness the wasted mechanical energy brought forth by the fluid energy. These flow-induced vibrations are quite abundant sources of energy in nature and are quite underused, so integrating S-TENGs into existing applications could help to harness this wasted energy source. Flow-induced vibrations are low frequency, high amplitude oscillations which are brought forth from an object being immersed in a flowing fluid. By capturing the energy of flow-induced vibrations, the fluid energy can be converted to mechanical energy followed by electrical energy. In this current project, our goal is to find the optimum set of S-TENG design parameters to produce the highest power output with the best efficiency. This will be achieved by understanding the role of system parameters plays in the power generation mechanism, such as the resistance in the electrical circuit, the contact area of the two TENG plates, relative displacement of the TENG plates due to increased flow velocity, flow velocity, and the contact pressure between the two TENG plates. In addition, we are interested to better understand how the power produced is scalable in such S-TENGs so that if used for larger applications, we can characterize and predict scalable power and efficiency in such systems.

ECE - Master of Science Thesis Defense By: Timothy Chase
- Location: > See description for location
- Cost: FREE
- Contact: ECE: Electrical & Computer Engineering Department
- Description: Topic: Data Optimization for Power In Large Arrays Of Sensors
Location: Science & Engineering Building (SENG), Room 212
Abstract:
The continuous demand for larger and more complex sensors constantly drives the need for smarter, faster, and more powerful silicon. To make these technologies more accessible to power sensitive applications, careful implementation of power management needs to occur. This is especially true of Two Dimensional Sensor Arrays (TDSA). Each pixel in a TDSA has several subcomponents all of which need to be designed to carefully optimize power. As the pixels increase in complexity and generate more and more data, the data management portions need to scale as well. This thesis documents the design iterations and analysis of the data management logic for a medium scale two dimensional array of sensors. The examined sensor has five 16-bit registers of data that needs to be moved from the sensor measurement logic to an IO port for external processing. Various architectures for both the data management blocks, as well as their sub components were designed in Verilog, synthesized to transistors and simulated for power measurements. The conducted experiments show that the Row Shift-Pass multiplexing architecture provides a significant reduction in power over a traditional Single Shift Chain. Digital designers can use this information to create more power efficient and higher performance sensors to meet the needs of an evolving world.
Note: All ECE Graduate Students are ENCOURAGED to attend.
All interested parties are invited to attend. Open to the public.
