TRANSIENT RESPONSE OF A TWO-REGION DECAYING TEMPERATURE SURFACE PROBE.
A theoretical and experimental study of a two-region probe contacting the surface of a semi-infinite solid was performed. A probe of this type has long-range potential for measuring thermal properties of a solid material using only surface contact. The two-region probe consisted of an outer annular ring and an inner cylindrical plug assembly constructed of copper. Transient heat transfer was initiated by preheating the probe assembly to a uniform temperature and then contacting the flat end of the probe with the surface of a semi-infinite solid material. The temperature decay of the inner and outer regions of the probe was monitored for a wide range of thermal contact resistances and solid materials. Experimental measurements of the probe response were compared with theoretical predictions.
