Use of Thermal Imaging for Chemical Engineering Education

A thermal camera was employed to transform the abstract ideas of the three primary modes of heat transfer: conduction, convection, and radiation into observable phenomena. Images and videos of boiling water, chemical reactions in hand warmers or heat packs, electrical heating pads, and vehicles were compiled to illustrate key heat transfer phenomena. Captions were used to describe the phenomena. In addition, explanations of how the thermal camera operates provide context for these observations.

Learners can perform experiments using household items, showing that experiments are not limited to the laboratory. Both the visuals and brief explanations allow learners to consider how principles of heat transfer are applied in daily life. The aesthetically engaging photos make seemingly intimidating and complex concepts more approachable. While this project showcases basic examples and concepts of heat transfer, it will inspire the audience to learn more and become interested in chemical engineering content related to heat transfer.

Beyond this project, thermal imaging has various applications such as security, gas detection, heat loss in buildings, and monitoring health. This project lays the groundwork for integrating thermal imaging into the chemical engineering curriculum as a part of the transport sequence.
