Abstract
A method is proposed for the simultaneous imaging of temperature and velocity fields inside combustion chambers to enable experimental data on turbulent heat fluxes needed for model validation and development. Applications include turbine engines, afterburners, internal combustion engines, and boilers. Temperature imaging is proposed with laser-induced luminescence imaging of phosphor particles suspended in a reacting gas flow, based on a combination of spectral and temporal luminescence characteristics. The same particles are used simultaneously for tracking fluid motion using the well developed method of Particle Image Velocimetry (PIV), enabling simultaneous images of temperature and velocity distributions. The presented Phase I work plan focuses on phosphor particle design, on the experimental demonstration of feasibility and on an analysis of precision and accuracy of several gas-phase thermographic phosphor imaging approaches.
