Abstract

The Temperature Sensitive Paint (TSP) is a widely used method in measuring and visualizing flow separation and heat transfer. Compared to the cost and time consumption needed for methods such as pitot tubes, temperature sensitive paint is a cheaper alternative. Due to high usage in College of Engineering research projects, it was determined that in house fabrication of temperature sensitive paint would reduce time and cost limitations. For initial stages, literature research was performed to determine the recipe of intensity based TSP with luminophore and polymer binder that operated optimum at temperatures from 0-100°C. Europium III thenoyltrifluoroacetonate was determined to be an effective luminophore to create a solvent for turbine cooling and heat transfer research. Standard operating procedure was also created such that it met the environmental and safety risk factors associated with fabrication of paint. Using acrylic glass test piece with existing experimental setup, intensity data were obtained. Experiments resulted in intensity change magnitude and Arrhenius curve similar to commercially available TSP. In addition, in-house TSP was significantly cheaper and less time-consuming. Further research would involve calibration curve and developing a Pressure Sensitive Paint.
