Differential, difference, and integral methods of measuring temperature dependence of coefficient of thermal conductivity
- 20 Downloads
A “temperature-step method” is proposed for the measurement of temperature distribution along a sample from which a differential coefficient of thermal conductivity is determined. The physical meaning of the difference coefficient of thermal conductivity as an average value for a given temperature range is emphasized. The possibility of making exact measurements of an integral coefficient of thermal conductivity is justified.
