Note:
SAMs 1.1.4 In the proposed effort, we plan to purchase upgrades to UTSA’s high-power pulse-burst laser that will increase power/repetition rate/pulses-per-burst ~10x and—when combined with existing equipment and the new Mach 7 wind tunnel at UTSA—will enable the development & implementation of a suite of measurement techniques that will provide time-resolved 2D and 3D (often referred to as 4D) visualization and quantitative measurements of key physical quantities of hypersonic flows not possible with the current system. These measurements will be the first of their kind in a hypersonic fluid flow and will provide validation-quality data for computational models. The measurements have potential applications in many flows of interest to the DoD including in studies of turbulent transition, shock-wave/boundary-layer interaction unsteadiness, and non-equilibrium flows. These tools will also be developed with an eye towards future implementation in large-scale DoD test facilities with a future technology transition being a key long-term goal of this research thrust.
