Modeling the process of autoclaving treatment of cellular concrete products as control object

Abstract

The authors consider the questions of modeling the process of autoclave treatment of cellular concrete products as a control object. The modeling method, performed in several stages, is suggested. At the first stage, a mathematical model of energy processes occurring in an autoclave, taking into account the internal heat generation during the formation of tobermorite in raw cellular concretes, is developed. The temperature dynamics of steam in an autoclave T n (t) has been determined. At the second stage, heat transfer in a cellular concrete is modeled for a given value of T n (t). As a result of computational experiments, the temperature dynamics T m (x, y, z, t) in the most characteristic parts of the cellular concrete was determined. The assessment of the adequacy of the developed model was made by comparing the results of modeling with the results of experimental studies obtained with the existing process equipment.
