Comment to the article ``On thermal waves velocity: some open questions in thermal waves physics'', Rev. Mex. Fis. E {62} (2016) 1-4
Keywords:
Heat transfer, thermal waves, second soundAbstract
It is showed here that an upper limit must exist for the speed of thermal waves because Fourier's laws of heat conduction cannot be used at very short length scales, but only over a length larger than the mean free path of the heat carriers.Downloads
