Heat and mass transfer.

Abstract

The present book in no way replaces the published reference book on thermal engineering and heat transfer, since first, it uses a new methodological approach and second, analyses mainly simultaneous heat and mass transfer processes and mathematical transfer theory, which may equally be applied to transfer of heat and mass. Therefore, radiative heat transfer, pure heat transfer and other problems of heat transfer are not considered in the book. Much attention has been paid to analytical theory of heat and mass transfer, particularly to unsteady-state heat conduction problems (Sec.2), where introduction of generalized functions has allowed the author to describe simultaneously one-dimensional temperature fields in classical geometries, to give a new, simpler description of propagation of temperature waves, to generalize regular regimes of temerature heating and to make some other generalizations. As a further development of the analytical heat-conduction theory the author presents the most recent solutions of differential heat and mass transfer equations (Sec.6), considers in detail hyperbolic heat- and mass-diffusion equations with regard to the finite rate of their propagation. This new approach to the description of heat and mass transger effects is related with the work done in the USA and dealing with mass diffusion in porous materials. (from authors abstract)
