Conjugate heat and mass transfer in continuous processes of convective drying

Abstract

Based on the previously developed mathematical model, heat and mass transfer in the initial period of drying and moistening of a continually moving material is studied in a conjugate statement of the problem. This approach allows one not only to take account of the effect of the external conditions on the processes in the material but also of the reverse influence which is exerted by these processes on the heat and mass transfer and which, in principle, cannot be allowed for by traditional calculational techniques based on the boundary conditions of the third kind. ru]Na ocNoвe paNee paзpaбoTaNNoй мaTeмaTиkhcyecкoй мoдeли иccлeдoвaN Teплoмaccooб-мeN в NakhcyaльNoм пepиoдe cyгцки и yвлaжNeNия NeпpepывNo движyщeгocя мaTepиaлa пpи coпpя-жeNNoй пocTaNoвкe зaдakhcyи.
