摘要: 基于经典的毛细管测量流体黏度原理,提出一种新型的测量高温高压条件下的单相介质流体黏度的方法及实验设备.经过误差分析,该方法具有1.009%的测试误差.利用该方法对蒸馏水的动力黏度(2 MPa,295~400 K)进行了标定实验,实验结果表明动力黏度测量的平均偏差小于0.715%,其最大偏差不超过2.3%.然后对国产航空煤油RP-3在压力0.1~2 MPa下,温度为298~744 K下动力黏度进行了测量.该方法适用于均一的牛顿流体.

Abstract: A new experimental method and apparatus were developed for the measurements of dynamic viscosity of fluids under high temperature and high pressure conditions based on classical capillary tube method. This method has an uncertainty of 1.009% according to the error analysis. Validation experiments were performed to measure the viscosity of distilled water (2 MPa, 290-400 K). The test results demonstrate that the average absolute deviation (AAD) is below 0.715%, and the maximum absolute deviation (MAD) is 2.3%. And then the dynamic viscosity of aviation kerosene RP-3 was measured under 298-755 K and 0.1-2 MPa. This method can be applied to any homogeneous Newtonian fluids.
