【摘要】 压力敏感涂料测量技术以其测压范围广、对流动干扰小等优点应用广泛。以叶轮机械内部流场测量为目的,以国产涂料为对象,在国内首次自主构建了压力敏感涂料测量系统,并对涂料进行了校准实验尝试,检验了测量系统的性能,基本摸清了涂料压敏特性和使用寿命,为进一步开展研究奠定了基础。更多还原

【Abstract】 Pressure-sensitive Paint Measurement(PSP) Technique has been employed in more and more fields for its unique advantages such as large pressure measurement surface,less interference to fluid field and so on.A PSP Measurement System for turbo-machinery has been established on the basis of equipment in existence for the first time in our nation.Calibration for homemade fluorescent PSP has been conducted in an attempt both to validate the PSP Measurement System and to have as more knowledge of homemade PSP as possible,such as its characteristic of fluorescent intensity versus pressure and its period of validity for use.All of the work prepared the ground for the farther research.更多还原
