Investigation of radiation-convective drying of fabric with the help of criterions of similarity of thermal transfer

Abstract

Results of research of radiation convective drying of fabrics are stated. Dependences of criterion of Boltzmann for a damp body from key parameters of drying kinetics are established. The empirical equations for calculation of time of drying, temperatures of a material and thermal streams are given in the period of the decreasing speed. Methods of the theory of similarity of heat exchange and the theory of a regular thermal mode of heating of damp bodies were used during the processing of experimental data.
