Uniformity Study of Two-Functional Luminescent Dyes Adsorbed over an Anodized Aluminum Coating for Motion-Capturing Pressure- and Temperature-Sensitive Paint Imaging.

摘要: The pressure- and temperature-sensitive paint (PSP/TSP) technique, for steady-state unsteady-state measurements, is becoming widespread. However, unsteady quantitative measurement still difficult because non-uniform distribution of the probes over a test model may cause errors in results. We focus on dipping method that applies two luminophores into binding material to improve sensitivity uniformity surface. A bullet-shaped axisymmetric with motion-capturing TSP was used evaluate uniformity, three methods (static, convectional, rotational) were examined. average peak ratios longitudinal direction 1.17–1.46 static, 1.38–1.51 1.42–1.45 rotational dipping. standard deviations transverse smallest (0.022–0.033), relative static (0.086–0.104), convectional (0.044–0.065)
