| Abstract: | A one-dimensional motion of an incompressible fluid (gas) through a fixed bed of a granular material under a short thermal pulse at the bed inlet is considered. An analytical dimensionless solution of the boundary-value problem is presented in quadratures. Specific features of the propagation of convective thermal waves due to the fluid (gas) flow are studied. The data on the propagation velocity, amplitude, temperature difference between the fluid (gas) and the bed, and the length of the zone of intense heat transfer are obtained. The examples of the analysis of a continuum flow in engineering apparatuses which use convective thermal waves are presented. |
