Irrigación, México, 11500, D.F., México. e-mail: emarin@ipn.mx Received 24 February 2016; accepted 29 March 2016 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. Keywords: Heat transfer; thermal waves; second sound. PACS: 51.20.
d; 66.10.Cb; 36.40.Sx; 68.35.Fx In a recent article published in this journal [1] some considerations about thermal waves are presented, in particular about their velocity.
It is showed that for thermal waves resulting from the solution of the parabolic heat dif...
