INFLUENCE OF MOISTURE EVAPORATION FROM A HEATED SURFACE ON THE THERMAL REGIME OF A CAPILLARY-POROUS BODY IN THE INITIAL PERIOD OF DRYING
S. N. Osipov,a E. V. Korobko, b and V. A. Bilykb UDC 536.12:621.6 The results of experimental determination of a change in time of the intensity of moisture evaporation from the surface of a ceramic mass for soft-mud moulding in the initial period and in a portion of the first period of radiant drying are presented. Comparison between the theoretical solution obtained for the Fourier equation with the corresponding boundary conditions and experimental results has been made, which showed an agreement sufficient for practical purposes. Nomograms convenient for practical applications are presented. a Belarusian National Technical University, 65 F. Skorina Ave., Minsk, 220072, Belarus; b A. V.
