Technical Field

Background

In the liquid film mass and heat transfer research process, the temperature of the liquid film needs to be measured. The temperature difference of different positions of the liquid film is not large, and if a plurality of temperature measuring elements are used for measurement, the problem that the error is too large and the measurement is inaccurate can be caused due to the difference of individual temperature measuring elements.

When the same temperature measuring element is used for measurement, because the liquid film is a cone, the temperature measuring point of the temperature measuring element is required to be adjusted in the horizontal direction and the vertical direction, the thickness of the liquid film is only 100-200 mu m, the temperature measuring area is small, and the fact that the temperature measuring point can be accurately measured on the liquid film by adopting a manual mode is difficult to ensure.

In addition, because mass transfer and heat transfer are dynamic processes, and the temperature changes along with the advance of time, the shorter the temperature measurement response time is, the better the temperature measurement response time is, so that the measurement speed of multiple points can be accelerated, and the time consistency of the measurement temperature of the multiple points on the liquid film is ensured.
