Abstract: A new design was presented of a portable transient hot wire apparatus for measuring the thermal conductivity of solids. The design features a two-wire sensor with silicon layers, compact printed electronic board and a high-tech software suite that utilizes the Finite Elements Method to model heat flow. This methodology is 120x's faster than any previous approach and can reduce the number of simulations required.
