摘要
压力敏感涂料(PSP)是一种全局压力测量技术.与传统压力传感器相比,PSP在快速旋转叶片上具有空间分辨率高和非接触等优势.然而,由于传统压力测量技术的局限性,PSP测量在高速旋转叶片上的验证非常困难.本文以中国空气动力研究与发展中心某型螺旋桨为研究对象,进行了PSP测量和计算流体力学(CFD)仿真研究.对不同工况下桨叶整体压力分布与CFD计算结果进行了比较.PSP测量结果与CFD计算结果具有良好的一致性.
Abstract
Pressure-sensitive paint(PSP)is a global pressure measurement technique.Compared with pressure transducers,PSP has significant advantages such as high spatial resolution and a lack of contact when applied to fast-rotating blades.However,due to the limitations of other pressure measurement techniques,the validation of PSP measurements on fast-rotating blades is generally difficult.In this paper,a comprehensive study including PSP measurement and simulation is conducted on a certain type of propeller at China Aerodynamic Research and Development Center.The global pressure distributions on the propeller blade obtained by PSP are carefully compared with CFD results under different working conditions.The results of PSP measurements and CFD show good agreement.
