本文运用文献〔4〕中提出的新热流法,在二维直角坐标系下开发了一个由热流方程和能量方程相结合的计算机程序。用该程序计算了高温炉内的辐射换热,得到了高温炉内的温度分布。这些模拟结果为研究高温炉膛内的热状态提供了重要的理论依据。作为一个例子,本文计算了马弗炉内的温度分布,与实测结果基本相符。
In this paper, a new heat flow method proposed in [4] is used to develop a computer program which combines heat flow equation and energy equation in two-dimensional rectangular coordinate system. Using this program, the radiation heat transfer in the high temperature furnace was calculated and the temperature distribution in the high temperature furnace was obtained. These simulation results provide an important theoretical basis for studying the thermal state in high temperature furnace. As an example, this paper calculates the temperature distribution in the muffle furnace, which is basically consistent with the measured results.
