The aim of this article is to determine the effective thermal conductivity of a composite material made of ellipsoidal coated inclusions bonded to a homogeneous isotropic matrix. The distribution of inclusions is considered to be periodic, nevertheless complex pattern can be investigated. An analytical ...
where k is the thermal conductivity of the wall material, A is the area of the surface normal to the heat flow direction, dx is the thickness of an elementary layer (of total thickness l), and θ is the temperature at the surface determined by the abscissa x. The temperature to the le...

blending method. The results show that the thermal properties of the composites are improved in comparison with the neat epoxy. Thermal conductivity value (0.587 W/mK) of epoxy composite with only 1.0 wt% Ti3C2MXene fillers, is increased by 141.3% compared with that of neat epoxy. In ...
Copper-graphene composite films with thickness greater than 200μm showed an improvement in thermal conductivity over that of electrolytic copper from 380W/m.K to 460W/m.K at 300K (27°C). The thermal conductivity of copper-graphene films decreased from 510W/m.K at 250K (–23°C) to ...

Note thatEquation 2.5predicts a thermal conductivity range of about 0.9–1.6 W/(m K) through 400 mbsf of hydrate zone. The mean value of thermal conductivity over the interval is 1.08 W/(m K). To estimate composite thermal conductivity of hydrate-bearing sediments, the generalEquation 2.6may...
The thermal conductivity of the products improved and the highest value obtained was 24.92%. The melting and solidification points decreased by one degree Celsius for the case of addition of nano-TiO2 and MgO and by 2 °C for the case of addition of the hybrid nanoparticles. Besides, the ...
