SiO2 soot preform sintering is a critical step in the indirect chemical vapor deposition (CVD) method for synthesizing high-quality silica glass, which involves hydroxyl (OH) decomposition, heat and mass transfer, as well as densification. These phenomena are not fully coupled in the traditional models, which leads to inaccurate numerical predictions. To address this, a porous media model with multiphase transport and solid mechanics bidirectional coupling (MTM) is proposed for the soot preform sintering process in this paper. The model is vali...
