摘要: 开发了一类微米级压敏荧光粒子。该粒子由表面多孔的空心二氧化硅（SiO2）粒子与压敏荧光材料（PtTFPP和Ru（dpp））融合而成。通过浸染方法使压敏荧光分子附着于粒子上，形成多功能示踪粒子，从而将粒子图像速度场测量技术（Particle Image Velocimetry，PIV）与压敏漆（Pressure Sensitive Paint，PSP）技术相结合，发展了一种流场压力与速度同步测量的技术，为流体力学研究提供一种崭新的实验测量手段。利用PSP静态与动态标定系统，对压敏粒子的信号强度、压力敏感性与压力响应时间进行了测量，研究了不同粒径和不同材料对压敏粒子性能的影响。测量结果表明，制备的压敏粒子具有较好的压力敏感性，其压力响应时间区间为40~70μm，符合测量流场瞬态压力的需求。分析了粒子在流场中的跟随性能，其中2μm粒子松弛时间为7.5μs，有较好的跟随性能。Abstract: A class of micron pressure sensitive fluorescent particles is developed. Porous hollow SiO2 particles and pressure-sensitive fluorescent materials (PtTFPP & Ru(dpp)) are used in these particles. Multifunctional tracer particles are prepared through attaching fluorescent materials to particles by the dip-dye method. Then a new simultaneous pressure and velocity measurement can be developed by combined Particle Image Velocimetry (PIV) technology and Pressure Sensitive Paint (PSP) technology. The signal intensity, the pressure sensitivity, and the pressure response time are measured by the static and dynamic PSP calibration system. Effects of different particle sizes and different materials on properties of pressure sensitive fluorescent particles are studied. The calibration result reveals that the pressure sensitive fluorescent particles have good pressure sensitivity, and the 40~70μs pressure response time is suitable for measuring the transient pressure in the flow field. The tracking ability is analyzed. The 2μm particles have 7.5μs relaxation time which show a qualified tracking ability.
