Quantifying The Threshold For Fragmentation Of Newtonian And Non-Newtonian Drops, Aditya Parik

All Graduate Theses and Dissertations, Fall 2023 to Present

This dissertation investigates how the properties of liquid drops influence the minimum aerodynamic forces needed to cause the drop to fragment (breakup). For this work, we focus only on aerodynamic forces that are applied on a stationary drop by a sudden, uniform flow, a process called impulsive acceleration. Previous studies have largely focused on the fragmentation of spherical drops of Newtonian fluids (liquids with constant viscosity, like water), when impulsively accelerated in air-like ambient medium. Such systems only capture a limited range of drop and ambient properties (described by non-dimensional groups). Many real-world applications, such as aerial fire retardant delivery, …

Calculation Of Aerodynamic Surface Sensitivities Using The Adjoint Method In A Subsonic/Supersonic Panel Code, Nathan H. Hoch

All Graduate Theses and Dissertations, Fall 2023 to Present

An aircraft’s shape has a direct impact on the lift and drag it produces. In the early stages of designing an aircraft on a computer, engineers work to improve aircraft performance and efficiency by considering various shapes and configurations. Engineers use computer programs to analyze different designs and predict how each would perform in real-world conditions. Once an approximate aircraft shape is selected, adjustments to the shape can further improve the aircraft’s lift and drag characteristics. Engineers calculate a set of values called sensitivities that indicate which parts of the geometry should be changed to increase lift or reduce drag. …

Quantifying Buoyancy-Driven Exchange Flows Over Obstacle At The Great Salt Lake Using Rans Cfd, Mohammad Ikram Hossain Talukdar

All Graduate Theses and Dissertations, Fall 2023 to Present

This study examines how barriers, such as berms, affect the movement of water in the Great Salt Lake in Utah. The lake experiences two types of water flow: one, called a unidirectional gravity current, where denser water flows in a single direction, and another, known as buoyancy-driven exchange flow, where water flows in two opposite directions due to differences in both water density and surface elevation. These flows are important for understanding how water mixes and moves between the northern and southern parts of the lake. Using computer models, we simulated how these two types of water flows behave when …

Investigating Stability Of Cone-Derived Hypersonic Waverider Vehicles Via Design Space Exploration, Adam S. Weaver

All Graduate Theses and Dissertations, Fall 2023 to Present

It may come as no surprise that man-made objects flying at 5, 10, or even 25 the speed of sound (termed hypersonic) are difficult to design, inefficient in flight, and expensive to deploy. Most hypersonic vehicles are effectuated in ballistics, which simplify aerodynamic considerations owing to their fixed trajectory. However, maneuverable hypersonic vehicles can revolutionize commercial flight, national defense, and space travel. One candidate for such missions are waverider vehicles. Waverider vehicles cruise on a cushion of air generated by its own shock wave, essentially enjoying extra lift without any extra drag penalties (which are usually inherent to extra …
