A Numerical Analysis of Heat Transfer of Glass-Lined Equipment

Glass-Lined material, which is sintered at high temperature, has different coefficients of thermal expansion, which is due to the residual strees created in the process of cooling the material to the viscoelastic material. However, self-cracks could be triggered in the stress affected area of buffer, when the stress exceeds the strength limit. Numerical analysis is adopted to solve the heat-transfer equations of glass lined material. Three-dimension Dougles and C-N method are used to gain the temperature field suited to cooling process of the the glass lined material. Tests show that the theory and method advanced in this paper are applicable to the process control of glass lined products, The numerical analysis is available for decreasing the residual stress and getting rid of the glass-cracking.
