Summary

A METHOD FOR DETERMINING THESURFACE TEMPERATURE AND SURFACE HEAT FLUX OF A ONE-DIMENSIONAL SOLID, IS DEVELOPED BY INTEGRATION OF DUHAMEL'S INTEGRAL WHICH INCLUDES UNKNOWN TEMPERATURE OR UNKNOWN HEAT FLUX IN ITS INTEGRAND. SPECIFIC FORMS OF SURFACE CONDITION DETERMINATION ARE DEVELOPED FOR SAMPLE INVERSE PROBLEMS: SLAB, HOLLOW CYLINDER, CYLINDER, HOLLOW SPHERE, SPHERE. IT IS SHOWN THAT THESE FORMULATIONS ARE CAPABLE OF REPRESENTING THE UNKNOWN SURFACE CONDITIONS EXCEPT FOR SMALL TIME INTERVAL FOLLOWED BY DISCONTINUOUS CHANGE OF SURFACE CONDITIONS. A SMALL TIME INTERVAL WHICH CAN NOT DESCRIBE ANY SURFACE CONDITION IS DEMONSTRATED BY A NUMERICAL EXAMPLE.
