A Tale Of Two Sides: Modeling Great Salt Lake Flows To Help Balance Current Ecosystem Influences, Eric Larsen

Research on Capitol Hill

USU senior Eric, hailing from Spanish Fork, studies mechanical engineering and funded this project through an engineering student grant. While there are several sampling stations that measure the waterflow of the Great Salt Lake, there are gaps in the data they collect that limit our ability to predict how water moves between the north and south sides of the lake. Eric has been developing machine learning models that more accurately portray the flows. This has applications for both GSL ecological preservation and the brine shrimp and salt industries. Eric loved how hands-on this project was, seeing the phenomenon that his …

Developing Silent Unmanned Aerial Vehicles, Glen Wright

Research on Capitol Hill

The optimization of a drone propeller’s acoustic signature can play an important role in the Department of Defense, observation of nature, commercial operations, and marine propulsion.

The aim of this research is to optimize the acoustic signature of propellers by isolating and modifying specific propeller characteristics. Propeller variations being researched in this project include:

• Leading-edge serrations: break up incoming fluid and evenly disperse it along airfoil
• Trailing-edge serrations: minimize vortex occurrences along the trailing edge of airfoil
• Airfoil ribs: force fluid through tangential channels along airfoil
• Winglets: disrupt turbulence and vortices at the tips of the propeller
