Abstract

The Phase I technical objectives of this program were to use existing lifetime based PSP technology and identify a combination of existing probes and binder that would provide a temperature-insensitive pressure sensitive paint (PSP). This was accomplished using the current lifetime-based systems that employ two-gate detection and by adding a second probe to the standard FIB pressure paint system. While the development of the temperature independent pressure paint was very successful, optimization of the entire acquisition system needs to occur. This Phase II program deals with the optimization of the entire time-resolved PSP acquisition system including: 1) paint system, 2) camera system 3) LED excitation system and 4) the development of particle based PSP. The goals of this program are to optimize the characteristics of each system component so that an enhancement in the entire system performance can be realized.
