Hi, I’m Bryan Chavez Kelly.
During my REU program at the FAMU-FSU College of Engineering, I worked on a project focused on flow control through the use of vortex generators under the mentorship of Dr. Rajan Kumar and Dr. Tuna R. Smith.
My research explored how varying the height of vortex generators affects surface flow characteristics, with particular attention to boundary layer behavior and vortex shedding. Using Particle Image Velocimetry (PIV) and signal processing, I analyzed velocity fields, vortex strength and distribution, and unsteady pressure signatures to better understand the dynamics of vortex-induced flow modifications.
This work contributes to improving aerodynamic efficiency by reducing drag and delaying flow separation — a key concern in aerospace and propulsion systems. The experience enhanced my skills in experimental methods, spectral analysis, and interpreting complex fluid dynamics behavior.
