hssadler42@tntech.edu
Hollee studied fluid-structure interactions of battle-damaged wings using our wind tunnel. In her research on a 3D printed wing section, she discovered that damage to the wing’s leading edge influenced the performance more severely. Her study also revealed that damages to the wing’s central section were worse than those occurring to the section’s tips. Hollee looked into several other parameters, including the dimensions of the damage. After receiving her M.Sc. degree, Hollee joined the University of Central Florida’s graduate school to pursue her Ph.D.!  

Madison Dittner
M.Sc. Student and Research Assistant (Summer 2018 – Spring 2020)
medittner42@tntech.edu
Madison’s research was focused on developing a numerical platform for geometry optimization. Madison developed a Genetic Algorithm that employs two commercial software packages (ANSYS and SolidWorks). The GA model assigns values to the parameters that are used to characterize the geometry of interest. SolidWorks makes the geometry and forwards it to ANSYS. Fluent module of ANSYS develops a CFD simulation for the new geometry and forwards results of interest back to the GA model. GA uses the simulation results to modify the geometric parameters. This continues until the optimal geometry is research. Madison uses TN Tech’s high-performance computing cluster to conduct CFD simulations. Madison is currently with the United States Patent and Trademark Office.
