Abstract
This paper describes an uncertainty analysis of simultaneous measurement of temperature and three- components of velocity by stereoscopic liquid-crystal thermometry and velocimetry using thermo-sensitive liquid-crystal particles and tracer particles. The uncertainty analysis of the measurement is carried out with the artificial stereo-color-images, which are generated from the numerical simulation data of thermal convection in combination with the experimental color characteristics of liquid crystals at various viewing angles. The results lead to the optimum stereo viewing angles for the measurement of temperature and velocity with high accuracy. It is also suggested that the accuracy of measurement can be improved by optimizing the number of particles, the pixel diameter of tracers and the intensity of the tracer particles.
