In the production process of synthetic quartz glass, the design of furnace and distribution and control of airflow field inside furnace affect the uniformity and temperature distribution of synthetic quartz glass, further affecting the physical properties and chemical composition uniformity of synthetic quartz glass. Therefore, the stability of airflow field inside furnace plays an important role in improving and synthesizing the production efficiency of synthetic quartz glass. The characteristics and related applications of synthetic quartz glass were introduced. In response to current problems of high temperature in furnace and inability to be tested, based on the research status of airflow field simulation at home and abroad, the current research progress in airflow simulation methods, simulation models and numerical calculation techniques were summarized. By comparing and analyzing various simulation methods and models, the application of computational fluid dynamics (CFD) method in the preparation of synthetic quartz glass was summarized. The development direction of multi physics field coupling applications was proposed, laying the foundation for optimizing the preparation process and product quality of synthetic quartz glass.
