Glass furnaces represent a continuous challenge for CFD simulations, which is attributed to the complex description of multiple phases: the turbulent gas phase, raw materials from a solid glass batch and the laminar liquid phase of the glass melt. Prevalence of unsuitable oxy-fuel combustion models, like the eddy-dissipation model, and the lack of advanced coupling methods for the coupling of combustion chamber and glass tank domains have been identified as research gaps in glass furnace simulations. These are tackled in a 3D CFD simulation model for an oxy-fuel glass furnace with electric boosting by introducing two significant improvements compared to previous approaches: (1) The partially-premixed steady diffusion flamelet model in combination with a skeletal25 reaction mechanism was used for combustion modelling. (2) An advanced iterative coupled simulation method is presented, which introduces damping of the solution and a rigorous termination condition. By employing the presented models, the respective temperatures in the combustion chamber and the glass tank were predicted within less than $1.93\%$ and $3.81\%$ of the experimental data.

玻璃熔炉是 CFD 模拟的持续挑战，这归因于多相的复杂描述：湍流气相、来自固体玻璃配合料的原材料和玻璃熔体的层流液相。不合适的氧燃料燃烧模型（如涡流耗散模型）的普遍存在以及燃烧室和玻璃罐域耦合的先进耦合方法的缺乏已被确定为玻璃熔炉模拟中的研究空白。与以前的方法相比，通过引入两个显着改进，在带有电增压的氧燃料玻璃熔炉的 3D CFD 模拟模型中解决了这些问题：(1) 部分预混稳定扩散火焰模型与骨架 25 反应机制相结合用于燃烧建模。(2) 提出了一种先进的迭代耦合仿真方法，该方法引入了解的阻尼和严格的终止条件。通过采用所提出的模型，燃烧室和玻璃罐中各自的温度被预测在小于$1.93\%$ 和 $3.81\%$ 的实验数据。
