Abstract

This paper presents preliminary results of common water thermal conductivity measurements using an all-fiber sensor based in conventional hot-wire method concept. The thermal conductivity of common water at room temperature obtained is 0.699 W/mK. Although the result is relatively distinct, about 14%, from the reference value found in literature, it is promising and indicates the feasibility of using the experimental arrangement for measuring thermal properties of materials with higher accuracy, provided that improvements already foreseen in future work be incorporated.
