Process and device for transient measuring of surface temperatures and heat flux

摘要

Process and apparatus for transiently measuring surface temperatures and heat flux at the interface of two media, one of which is solid. In a solid wall through which a thermal stream flows, a cut is made which opens into the interface between the wall and the other medium. The cut is parallel to the stream at a point of contact corresponding to the interface. A microthermocouple is arranged in a plane of the cut in the immediate vicinity of the interface. The cut is closely covered by the material of the solid wall or a material with thermal characteristics similar to those of the peripheral material.
