Abstract
Turbulence in compressible flows holds significant importance across various applications, such as optimizing air/fuel mixing in scramjet combustors. However, managing compressible turbulence presents distinct challenges compared to incompressible flows, as fluctuations extend to thermodynamic quantities, including density. Density fluctuations notably influence the production term of Turbulent Kinetic Energy (TKE). Despite advancements in velocity measurements, particularly in supersonic flows, density measurement remains inherently complex. This study focuses on further refining a turbulence density measurement technique utilizing shadowgraph imaging, tailored for application in the recently upgraded Missouri S& T supersonic wind tunnel. The developed technique will enable the student to quantify turbulent density fluctuations within the wind tunnel's free stream. Accurate quantification of free stream turbulence is paramount prior to initiating any experimental testing. The original development of this technique received recognition through an OURE scholarship in 2023, and its research proposal secured first place at the 2023 UGRC in the "research proposal poster" category.
