研究了利用热线技术监测停滞试液粘度的基本问题。理论上，结合竖板自然对流换热的Ostrach解和停滞层分析，较好地描述了热线粘度传感器的特性。为了提高传感器对测试流体粘度变化的灵敏度，建议采用较小的曲率和较高的热流密度作为传感器的工作条件，并进行了实验验证。作为一个实际例子，利用热线传感器监测了大豆蛋白凝聚过程中表观粘度的变化。
Fundamental aspects of the monitoring of viscosity by the hot wire technique in stagnant test fluid was investigated. The behavior of the hot wire viscosity sensor was well described, theoretically, by the stagnant layer analysis combined with the Ostrach solution for natural convection heat-transfer from a vertical plate. To improve the sensitivity of the sensor to the change in viscosity of a test fluid, lower curvature for the sensor structure and higher heat flux for the operating condition were recommended theoretically and proved experimentally. As a practical example, the change in apparent viscosity during the coagulation of soy protein was monitored using the hot wire sensor.
