The pressure- and temperature-sensitive paint (PSP/TSP) technique, for steady-state and unsteady-state measurements, is becoming widespread. However, unsteady quantitative measurement is still difficult because non-uniform distribution of the probes over a test model may cause errors in the results. We focus on the dipping method that applies two luminophores into a binding material to improve sensitivity uniformity over a model surface. A bullet-shaped axisymmetric test model with motion-capturing TSP was used to evaluate the sensitivity uniformity, and three dipping methods (static, convectional, and rotational) were examined. The average peak ratios in the longitudinal direction were 1.17-1.46 for static, 1.38-1.51 for convectional, and 1.42-1.45 for rotational dipping. The standard deviations in the transverse direction were the smallest for rotational (0.022-0.033), relative to static (0.086-0.104), and convectional (0.044-0.065) dipping.
用于稳态和非稳态测量的压力和温度敏感涂料（PSP/TSP）技术正在广泛应用。然而，非稳态定量测量仍然困难，因为测试模型上探针的不均匀分布可能导致结果出现误差。我们专注于将两种发光体应用于粘结材料的浸渍方法，以提高模型表面的灵敏度均匀性。使用带有运动捕捉TSP的子弹形轴对称测试模型来评估灵敏度均匀性，并研究了三种浸渍方法（静态、对流和旋转）。纵向方向的平均峰值比，静态浸渍为1.17 - 1.46，对流浸渍为1.38 - 1.51，旋转浸渍为1.42 - 1.45。相对于静态浸渍（0.086 - 0.104）和对流浸渍（0.044 - 0.065），旋转浸渍横向方向的标准偏差最小（0.022 - 0.033）。
