Fabrication of Fast-Responding, Luminescence-Enhanced micro-Spheres for the Digital Luminescent Particle Tracking Barometry Thermometry and Velocimetry System
Abstract
The goal of this proposed research is to create a novel and unique technique, capable of simultaneously measuring velocity, pressure and temperature through time. We will achieve this goal fabricating innovations we have developed in Pressure-Sensitive Paint (PSP) that we will also implement in Temperature-Sensitive Paint (TSP), and combining them with Particle Tracking Velocimetry (PTV). As part of this fabrication, we will replace the standard reflective PTV particle with microspheres (micro-Spheres) that are pressure and temperature sensitive. In this manner, the particle will not only provide a measurement of pressure and temperature, but through its motion, it will also provide velocities that can be extracted using current state-of-the-art PTV algorithms. In addition, these micro-Spheres will have fast response times on the order of microseconds in order to allow for studies of turbulent flows. This new measurement method will be referred to as Digital Luminescent Particle Tracking Barometry, Thermometry and Velocimetry (DLPTBTV). Such simultaneous measurements have never been obtained before, thus making this fabricated measurement method truly transformative, as it will allow for investigations that would lead to better understanding of turbulent flow physics, modeling of turbulence, aeroacoustics and noise generation, and hydroacoustics of underwater vehicles, and energy conservation through the promotion of better designed energy efficient devices.
