Abstract
During a process of building an experimental facility, the thermal bonding joint of organic glass bulk polymerization needs to be annealed by a heating belt with the heat flux density of 4200 W/m2. The excessive heat needs to be removed efficiently to avoid damaging the surrounding areas. In this paper, the cooling effect of the air supply velocity on the high heat flux surface is investigated using CFD simulations, while the air supply temperature and volume are kept constant between cases. The results show that the air supply velocity has a significant impact on the cooling process of the high heat flux surface. With the increase of air supply velocity, the maximum and average temperature of the high heat flux surface decrease significantly. In addition, the cold air of large velocity could effectively suppress the spread range of hot air. These results provide a reference on the further study of organic glass annealing process.
