- An experimental study on emission characteristics of PSP in low oxygen partial pressure region
抄録
<p>In recent years, pressure distribution measurement with high accuracy by PSP (Pressure Sensitive Paint) has been performed for high-speed moving objects with large pressure changes. However, there remains a problem in measuring pressure around low-speed moving objects such as small rotating machines, because the pressure sensitivity of PSP near atmospheric pressure is too small. In the present study, the effects of oxygen partial pressure on the static properties of PSP were investigated. Sample coupon tests using a vacuum container were conducted for PdTFPP/Poly(IBM), PtOEP/Poly(IBM), Ru(dpp)3/Poly(IBM) and Ru(dpp)3. The oxygen partial pressure was set to be between 2 - 10 kPa (with an interval of 2 kPa) and the total pressure was set to be between 20 - 100 kPa (with an interval of 20 kPa). The intensities of PSP emission, that are normalized by the maximum intensity in oxygen partial pressure = 0 kPa, i.e., the relative intensity of PSP emission, decreases with the increasing of oxygen partial pressure. Total pressure had almost no effect on the relative intensity change of tested PSP. The relationship of the rate of change in relative intensity is Ru(dpp)3/Poly(IBM) > Ru(dpp)3 > PtOEP/Poly(IBM) > PdTFPP/Poly(IBM). Ru(dpp)3/Poly(IBM) shows the highest pressure sensitivity, where PdTFPP/Poly(IBM) shows the lowest pressure sensitivity between the tested PSP.</p>
