Identification models for transient heat transfer on a flat plat
Résumé
This paper presents new methods for identifying the convective heat transfer on a flat plate using analytical models bases on the Green functions theory. The air flows over a flat plate heated by applying a controlled and transient radiative heat flux to one of its surfaces. On the opposite surface, the plate is cooled by another air flow. The temperature profile of the plate surface is determined with an infrared camera when the plate is exposed to the controlled heat flux. Green functions are used to determine analytical solutions for the heat flux equation in the plate. These analytical solutions allow the transient convective heat transfer to be identified.
