Description

Periodic heat flow methods for measurement of the diffusivity of a material have proven to be highly effective methods dating back to the work of Angstrom. Typically, these measurements have involved a determination of the phase lag between a source applied to the surface and the temperature measured at the opposite surface. When the frequency of the periodic heating is well matched to specimen, it represents perhaps the most efficient thermal diffusivity measurement technique.
