Simultaneous determination of intrinsic solid phase conductivity and effective thermal conductivity of Kelvin like foams

Two models are derived in order to predict simultaneously intrinsic solid phase thermal conductivity, λs and effective thermal conductivity, λeff. A modified correlation factor, F is introduced in analytical resistor model in order to take thermal conductivities of constituent phases into account and a new PF model based on Lemlich model is derived. An excellent agreement has been observed between the predicted results against numerical and experimental data. We have also shown the importance of intrinsic solid phase thermal conductivity (λs) in determining effective thermal conductivity (λeff).
