提出了一种能够在储备罐中进行现场测量以评估瞬时粘度曲线的新方法。旨在满足工业生产过程中无需取样即可实时监测流变性能的实际需求。通过适用的剪切速率和粘度范围 O(10–1–102s–1) 和 O(10–2–100Pa·s)，可以基于超声纺丝流变测定法评估具有剪切应变速率依赖性的流体特性。由于该方法在改变储罐中的流体温度的同时评估剪切稀化粘度的特性，因此预计会有一些有用的例子作为在化学反应过程（例如凝胶化、水解和聚合）期间测量粘度的进一步应用。数值和实验结果验证了该方法评估流变特性的有效性。
A novel method enablingin situmeasurement in a reserve tank for evaluating an instantaneous viscosity curve is presented. This aims to satisfy the practical demand of industrial production process for monitoring real-time rheological properties without taking samples. With applicable ranges of shear rate and viscosity,O(10–1–102s–1) andO(10–2–100Pa·s), it enables evaluation of fluid properties having shear strain rate dependence, based on ultrasonic spinning rheometry. Since this method evaluates the characteristic of shear thinning viscosity while changing the fluid temperature in a reserve tank, some useful examples are expected as further applications for measuring viscosity during chemical reaction processes, such as gelation, hydrolysis, and polymerization. Efficacy of the method evaluating rheological properties is validated by numerical and experimental results.
