These types of heat flux have a wide range of applications in scientific research, industrial production, and daily life. For example, in industrial manufacturing, the temperature of the material throughout the processing process needs to be tightly controlled to establish the desired properties and quality control, which involves the precise measurement and control of heat flux.
