“…14). However, the accuracy of the hot wire method, used by Wang et al [124], has been questioned by Tian et al [126] who used the steady-state heat source method to evaluate the heat and mass transfer of a compact impregnated CaCl 2 eEG. The highest thermal conductivity (1.70 W m K À1 ) is reached when the mass fraction of EG in the composite is 50% and the density of the composite is 550 kg m À3 .…”
