Effective Thermal Conductivity in Free convection Formulas

Effective Thermal Conductivity is the rate of heat transfer through a unit thickness of the material per unit area per unit temperature difference. And is denoted by k_Eff. Effective Thermal Conductivity is usually measured using the Watt per Meter per K for Thermal Conductivity. Note that the value of Effective Thermal Conductivity is always negative.
