Nondestructive evaluation (NDE) methods are being developed for thermal barrier coatings (TBCs) and for gas-separation membranes. For TBC applications, current NDE development is focused on infrared thermal imaging methods. Compared with optical and other methods, thermal imaging is quantitative so can be used to characterize TBCs during their entire life cycle, from as-processed condition to s...

Thermal conductivity is a fundamental parameter in every battery pack model. It allows for the calculation of internal temperature gradients which affect cell safety and degradation. The accuracy measurement thermal directly proportional to any calculation. Currently industry uses archaic methods measuring this property have errors up 50 %. This includes constituent material approach, Searle’s ...

The thermal conductivity of superconducting MgB 2 was studied in both the superconducting and normal state region. The latter is almost equally determined by the electronic-and the lattice thermal conductivity. In the superconducting state, however, the lattice thermal conductivity is larger. The electronic thermal conductivity below T c was derived from the experimental data considering the Ba...

cement production is an energy-intensive process, so that the cement industry occupies a top position among other energy-consuming industries. among the equipment used in cement industries, boilers are one of the energy-consuming equipment. boilers are among the common heating equipment in industrial, commercial, and institutional facilities. in this paper, the performance of thermal oil boiler...
