Heat Transfer Due to Thermoelastic Wave Propagation in a Porous Rod

This paper investigates the propagation of theremoelastic waves in a homogeneous, linear and isotropic porous solid. For physical and mathematical simplicity, a one-dimensional solid bar is used to explain the concept of heat transfer caused by motion. Solution of governing equations shows that the transfer of heat in a one-dimensional porous rod is not only due to the conduction but also produced by the local particle displacement phenomenon. It is observed that the time-averaged transfer of heat depends on the circular frequency, porosity, thermal conductivity, thermal relaxation, specific heat and other material coefficients.
