Biography
Joseph Villarreal is a fourth-year aerospace engineering undergraduate student at Missouri University of Science and Technology. He is from Columbia, Missouri where he graduated from Hickman High School before enrolling in college. Halfway through his third year in college, he joined the Aerodynamics Research Laboratory led by Dr. Vigano, where he spent a semester refurbishing the supersonic wind tunnel’s high-pressure compressor. After that was completed, he started the two-point Focused Laser Differential Interferometry project. Looking towards the future, he wishes to continue his academic career and research project into a master’s thesis program, also at Missouri University of Science and Technology.

Abstract:
This research project focuses on the design, construction, and testing of a two-point Focused Laser Differential Interferometry (2-FLDI) system for integration into the Missouri S&T supersonic wind tunnel. FLDI is a non-intrusive, laser-based technique for measuring high-frequency density gradients in compressible flows. In a 2-FLDI setup, the input beam is further split into two pairs, each detected by a dedicated photodetector. By tracking coherent structures with similar density gradients between these pairs, velocity measurements can be obtained based on the known inter-beam distances. This work includes the system’s design, assembly, and validation within the wind tunnel environment. The successful implementation of 2-FLDI will enhance the facility’s diagnostic capabilities, enabling more precise characterization of supersonic flow structures.
