热力计算的布林克莱法,经常在三氧化二铝的相变温度附近,遇到迭代不能收敛的现象。这是由于计算截面进入三氧化二铝的相变区间,燃烧产物中同时存在着液态和固态二氧化二铝,而布林克莱法则要求同种物质在燃烧产物中只能有一种凝聚相所引起的。本文提出可以处理相变过程的一种计算方法,考虑了固液两种相态三氧化二铝的影响。具有处理相变过程功能的热力计算程序,给出了满意的结果。
The thermal calculation of the Brinker method, often in the vicinity of the phase transition temperature of aluminum oxide, encountered the phenomenon of iteration can not converge. This is due to the fact that the calculated phase transitions into the phase change zone of aluminum oxide with the simultaneous presence of liquid and solid aluminum oxide in the combustion products and that the Brinkley’s law requires that the same species have only one phase of agglomeration in the combustion products caused. This paper presents a calculation method that can handle the phase transition process, taking into account the influence of solid and liquid two phases of aluminum oxide. A thermodynamic calculation program that handles the phase change process gives satisfactory results.
