Mathematical Simulation of Porous Glass Thermal Processes at Annealing Stage

[摘要] The mathematical model of the porous glass heat field under conditions of complex heat exchange in the process of the technological stage of annealing is presented. The model includes calculations of the radiation, convective and molecular components. The mathematical model is based on the finite element method. The model is realised in the software Ansys. The statement of the problem is given. The object under study, i.e., model structural features, is presented. The method of model structure obtaining, the initials and boundary conditions are given. The theoretical basis of the methods, approaches and of the optimal calculation parameters choice principles are presented. The estimation of the model adequacy by means of the experimental verification is given. The comparison of the obtained data with the experimental results is performed. The relative error of calculation using the developed model does not exceed 15%.
