The thermal conductivity of Cu powder modified thermoplastic polyimide(TPI)was mea- sured via stable thermal plate method.The effects of filler content on the mechanical properties and thermal conductivity has been investigated,the relation between temperature and thermal conductivity of Cu/TPI composites...
We present a systematic theoretical investigation of the thermal conductivity of naturally abundant, isotopically enriched, fast neutron irradiated single crystals of diamond, and chemical vapor deposited diamond films of different types over a large temperature range. Existing experimental data have been an...
Hence, only an approximate power law-relation between conductivity and effective temperature can be established, as indicated by the dotted line in Fig. 5b. This observation is in line with earlier works concluding that the effective temperature is an approximate concept only23,24,25. However, it...
On a more local scale the correlation of electrical conductivity with temperature and state of the material seems to be more realistic. This is tentatively shown by two petrological models of the Afar depression in Ethiopia and of the midoceanic rift....
Temperature and thermal conductivity measurements from a 880-meter drilled hole (35°54.66N, 84° 18.94W) at Oak Ridge National Laboratory, Oak Ridge, Tennessee, give a value of 0.73±0.04/cal/cm2 sec for the flow of heat from the earth's interior. A detailed study of the thermal conduct...
A new transient state identification method is proposed based on the niche genetic algorithm to identify the relation between thermal conductivity and temperature from the transient thermal response. The temperature-dependent thermal conductivity of four thermal protection materials are finally obtained. The...
The temperature was raised in steps to the highest value, and red was maintained within u±ce2d° in C. similar fashion. It of any required value until tho conductivity reached equilibrium value. Because of the smallness of the currents being measured, the accuracy was rather low at the ...
It is clear from the figure that there is a linear relation between thermal conductivity augmentations with temperature rise. High nanofluid temperature intensifies the Brownian motion of nanoparticles. With intensified Brownian motion, the contribution of microconvection in heat transport can also be ...
PCMs with higher thermal conductivity conduct more heat than those with lower conductivity for a given temperature. Thermal conductivity of organic and salt hydrates are between 0.2 and 0.5 W/mK [111], which is considered low to charge and discharge of the latent heat during the phase change. ...
