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 ...
The effective thermal conductivities of fully expanded intumescent chars are estimated using a finite element model related to porosity and density of the chars....
