where ρ is the density of the medium, C is the thermal (heat) capacity, k is the thermal conductivity, coefficient of heat conduction, Q is the heat source, h θ is the convective heat transfer coefficient, θext is the external temperature.
where qcond is the heat flux generated by conduction, Ccond is the thermal conductivity coefficient, and ( frac{partial T}{partial X} ) is the temperature gradient.
Moreover, an optimal thermal conductivity coefficient that corresponds to the peak power output exists when the conduction along the exchanger is considered.
k thermal conductivity coefficient.
k Thermal conductivity coefficient (Wm/K).
k thermal conductivity coefficient (W/m/K).
Finally, we measured the thermal conductivity coefficient of these materials.
The thermal conductivity coefficient is reduced with increased temperature.
The influences of some key factors (half apex angle, thermal conductivity coefficient, radiant emissivity, etc).
These activities require the determination of thermal conductivity coefficient of rocks especially around underground openings.
The effect of moisture and coniferous tree species on the thermal conductivity coefficient was determined.
