New independent representations of the viscosity and thermal conductivity of ethane in the limit of zero density. For viscosity, the correlation is over the temperature range of 200 to 1000 K, with the highest uncertainty being 2.5% . The correlation for thermal conductivity covers from 225 to 725 K with a highest uncertainty of 3%....
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 ...
