Sensor fusion to improve state estimate accuracy using multiple inertial measurement units and its application to wind estimation
(2021-12)
On-board state estimation is a persistent challenge to fielding unmanned aerial systems (UAS), particularly when global positioning system (GPS) measurements are not available. The dominant estimation tool remains the ...
Control and commissioning of a hot-gas bypass compressor load stand for testing light-commercial compressors using low-GWP refrigerants
(2020-07)
As a result of changing efficiency standards for HVAC&R equipment, hydrofluorocarbon refrigerants such as R134a and R410A are in the process of being phased out because of their high Global Warming Potential (GWP). Many ...
Design and development of a water observatory: An autonomous environmental sampling system for in-situ sensing of lakes and rivers
(2020-12)
This project focuses on the design, development, and implementation of an autonomous system, or unmanned surface vessel (USV), known as MANUEL (Mobile Autonomously Navigable USV for Evaluation of Lakes). MANUEL is an ...
Efficacy of SOLIDWORKS Flow Simulation for use in thermal management and propulsion systems cooling of unmanned aircraft systems
(2021-05)
As the capabilities of unmanned aircraft systems (UAS) expand, optimizing the thermal management designs become increasingly important. SOLIDWORKS Flow Simulation is a powerful and accessible tool that has the potential ...
Project Monarch: The application of Ludwig Prandtl's bell-curve span loading to a straight, high performance sailplane wing
(2021-07)
This thesis focused on the design considerations and application of Ludwig Prandtl's 1933 bell-curve span load to a high performance, straight aircraft wing. Sailplanes are designed to maximize lift-to-drag ratio and reduce ...
Parametric optimization of lattice structure heat sinks: An integrated computational and experimental approach
(2023-05)
Lattice structures have frequently been investigated for their unique mechanical and thermal properties and have been optimized for better performance for these characteristics. Their mechanical properties have shown amazing ...
Development and commissioning of a variable capacity experimental infrastructure for a novel three fluid heat exchanger
(2023-05)
One of the major problems with using renewable energy is the mismatch between power generation and demand as renewable energy generation and energy usage from HVAC equipment depend on unsynchronized natural factors. To ...
Characterization of degraded drag-reducing polymer solution and its impact on the structure of turbulence
(2019-12)
Turbulence is often described in terms of either a random process or interacting coherent structures, which is really a choice of which parts of the turbulence to ignore. Focusing on coherent structures reducing the ...
Design and construction of a pumped refrigerant loop for commercial scale low-GWP refrigerant heat exchanger testing
(2021-07)
A pumped refrigerant loop for refrigerant conditioning is developed to allow testing of heat exchangers using a wide range of refrigerants, including low global warming potential refrigerants. The pumped refrigerant loop ...
Development of a dolphin hormone sample collection device for UAS
(2021-07)
Marine biologists are able to quantify the stress in dolphins through analysis of hormones in mucus samples released from the blowhole while breathing. This method provides a noninvasive approach compared to current methods ...
