Abstract
The purpose of this thesis is to describe the logic behind the extension of a test section in a facility that was designed for studying fully developed turbulent boundary layers in wall-bounded flow, primarily using Particle Image Velocimetry (PIV). The initial section will focus on providing motivation of why it can be of interest to study turbulence. The following section will provide a historical context of the development of the Navier-Stokes equations which attempt to mathematically model the behavior of fluid elements from a microscale. These fundamental equations will then get expanded to demonstrate how they fit with the modern look at turbulence. Finally, the rest of the document will build on these historical principles. The bulk of the thesis will cover the design methodology and some experimental data which proved a degree of success after the tunnel was assembled and instrumented. Concerns about stability regarding ensuring a structurally sound TS, and mitigating natural frequencies will be addressed. This will then be followed by plans for future experiments and some recommendations regarding areas of improvement.
