Angstrom configuration for absolute measurement on heat losses of a metal sample by active thermography

 Six researchers, lead by Teodoro Cordova from the Universidad Autónoma de Zacatecas (Mexico), have recently published a paper in the Infrared Physics & Technology journal. The paper title is “Angstrom configuration for absolute measurement on heat losses of a metal sample by active thermography” and it is available online on the journal’s page.

The paper demonstrates an experimental setup and an optimized method to evaluate the averaged heat loss coefficient of a metal sample surface without knowing the thermal properties of the sample. The heat loss coefficient was measured using a thermal camera and greenTEG’s gSKIN XI heat flux sensors. The obtained results were validated by comparing them with numerical COMSOL simulations. The advantage of experimentally measuring the heat loss coefficient is that minimal assumptions have to be made and the underlying, complicated theoretical model does not have to be adjusted. The study further showed that the heat loss coefficient does not depend on the thermal properties of the metal sample nor the operating mode (heating/cooling).

We congratulate the researchers for this interesting piece of science, and we appreciate they are using our sensors to run accurate and responsive measurements. Good job!
