Characteristic time of thermal and diffusion relaxation
© O.V. Aryasova, Y.M. Khazan, 2015
It is shown that frequently used dimensional estimate of a layer thermal relaxation time, , as
L2/ê based on the layer thickness, L, and thermal diffusivity, ê, strongly overestimates
The correct estimate
should contain a factor of which is of the order of 0.1.
Key words: characteristic time, thermal relaxation.
