本文详细介绍了一个能够模拟大型加热炉瞬态热工性能的第一性原理混合模型的开发。特别是，新的建模方法结合了辐射分析和计算流体动力学（CFD）在一个强大的方式的经典区域方法的优点，并克服了困难，将三维流场内的区域方法为基础的模型。所开发的模型已被验证与全面的实验数据收集在仪表化的大方坯试验期间，包括一个长的生产延迟。结果表明，模型预测与实际测量结果吻合良好，并且模型能够正确响应试验期间遇到的生产延迟。
This paper details the development of a first-principles hybrid model capable of simulating transient thermal performances of a large scale reheating furnace. In particular, the new modelling approach combines the advantages of the classical zone method of radiation analysis and Computational Fluid Dynamics (CFD) in a robust manner, and overcomes the difficulties of incorporating three-dimensional flow field within a zone method based model. The developed model has been validated with comprehensive experimental data collected during an instrumented bloom trial period that includes a long production delay. The results suggest that the model predictions were in good agreement with the actual measurements, and that the model was able to respond correctly with respect to the encountered production delay during the trial.
