Abstract

Flow velocimetry techniques and Temperature Sensitive Paints, (TSP), requires working with different laser beam intensities. Because velocity flow measurements needs high level laser power compared with temperature surface measurement, where lower levels of laser power is required, is necessary to adjust the system to avoid the damage of the paint due to the high intensities in laser velocimetry measurements. The use of paint of different grey levels (from white to black) as backgrounds above the TSP film deposition allows to make temperature measurements with high laser power without damaging the TSP. This work is centered in the characterization and testing improvements of the temperature surface measurements using Temperature Sensitive Paints as a part of the 3D tunneling velocimetry system.
