将热线技术应用于无挡板搅拌槽中流体粘度的监测。将Kramers方程与复合涡模型相结合，可以很好地描述垂直放置在容器中的热线粘度传感器的行为。通过增加热线的热流密度，提高了传感器的灵敏度。利用该传感器，监测了马铃薯淀粉溶液在α-淀粉酶作用下的粘度变化。
The hot-wire technique was applied to the monitoring of the viscosity of a fluid in a nonbaffled agitated vessel. The behaviour of the hot-wire viscosity sensor placed vertically in the vessel was described well by the Kramers equation combined with the compound vortex model. The sensitivity of the sensor was found to be improved by increasing the heat flux from the hot wire. With this sensor, the change in the viscosity of a potato starch solution was monitored during hydrolysis by α-amylase.
