Estimation of thermal conductivity of Na–K liquid metal alloy

For the first time the thermal conductivity of Na–K alloy has been computed using eight theoretical equations, already developed for binary liquid mixtures. The thermal conductivity values of Na–K alloy were obtained at three different temperatures (308,348,423) K, and at four different compositions of alloy. We have employed density and sound speed data for calculating λ alloy with the help of recently developed correlation. Density-Sound speed-thermal conductivity correlation gave excellent results.
