Datasets of measured viscosity of Polyalpha-Olefin- boron nitride (PAO/hBN) nanofluids are reported. An AR-G2 rheometer (from TA Instruments) experimental setup is used for measuring the rheological property of PAO/hBN nanofluids, which is a combined motor and transducer (CMT) instrument. The test fluid sample size is approximately 1.5 ml and the tests were conducted over a temperature range of the tested fluids from - 20 °C to 70 °C by a water circulator chamber. The dataset includes measured viscosities as a function of the BN volumetric concentration () of 0, 0.6 and 1%. Two sets of viscosity measurements are conducted insuring the thermal equilibrium conditions are reached for all experiments. In set (1), the viscosity is measured at intervals of 10 °C by fixing the temperature at each interval (at -20, -10, 0, 10, 20, 30, 40, 50, 60 and 70 °C), while the shear stress and shear rate are varied. In set (2), the temperature is varied from -20 °C to 70 °C at intervals of 0.5 °C, while the shear stress is fixed and the shear rate is varied accordingly. Set (1) is designed to verify whether the fluids are Newtonian or not and set (2) is designed to derive correlations for the viscosity as a function of temperature. Several characteristics data are recorded including rotational speed of the spindle (RPM), torque, viscosity (Pa- s), shear stress (Pa), shear strain rate (1/s) and temperature (°C). The reuse potential of the dataset includes calculating Reynolds number for further flow studies; heat transfer performance studies of nanofluids; lubrication and lubricants' development studies and characteristics of Newtonian and non-Newtonian fluids. The dataset reported here were used (but not published) in the article published by the author in [1] (https://doi.org/10.1016/j.csite.2020.100776).
报道了聚α-烯烃-氮化硼（PAO/hBN）纳米流体的测量粘度数据集。使用AR-G2流变仪（来自TA仪器公司）实验装置来测量PAO/hBN纳米流体的流变特性，这是一种组合式电机和传感器（CMT）仪器。测试流体样本量约为1.5毫升，通过水循环腔在-20°C至70°C的测试流体温度范围内进行测试。该数据集包括在BN体积浓度（）为0、0.6%和1%时测量的粘度。进行了两组粘度测量，以确保所有实验都达到热平衡条件。在第（1）组中，通过在每个间隔（-20、-10、0、10、20、30、40、50、60和70°C）固定温度，以10°C的间隔测量粘度，同时改变剪切应力和剪切速率。在第（2）组中，温度以0.5°C的间隔从-20°C变化到70°C，同时固定剪切应力并相应地改变剪切速率。第（1）组旨在验证流体是否为牛顿流体，第（2）组旨在得出粘度与温度函数的相关性。记录了几个特征数据，包括主轴转速（RPM）、扭矩、粘度（Pa·s）、剪切应力（Pa）、剪切应变率（1/s）和温度（°C）。该数据集的再利用潜力包括计算雷诺数以进行进一步的流动研究；纳米流体的传热性能研究；润滑和润滑剂开发研究以及牛顿流体和非牛顿流体的特性研究。这里报道的数据集在作者发表于[1]（https://doi.org/10.1016/j.csite.2020.100776）的文章中被使用（但未发表）。
