第三类边界条件 meaning in English
third boundary condition
Examples
- Compared with other general cfd software , the numerical modeling software of combustion process improved by the author of this paper has following features : ( 1 ) it can adjust the corresponding parameters and manipulating methods according to furnace architecture , operational parameters and fuels etc . ; ( 2 ) it can arrange the nodes of grid flexibly and also make special calculation to certain nodes , which cannot be accomplished by the general commercial software ; ( 3 ) in the boundary ( water - cooled wall ) condition processing , the third boundary condition is selected for the temperature calculating , linking the combustion process inside the furnace with the flow and heat exchange of water inside the water - cooled wall , so the heat absorbing and the influence of the water - cooled wall to combustion process and heat transfer of furnace are explicitly explained
与其它通用的cfd软件相比，经论文作者所改进的燃烧过程数值模拟软件的特点在于： ( 1 )能够结合炉子结构、运行参数及燃料等，调整模型中相应的参数及处理方法； ( 2 )可以灵活的安排网格节点，对某些节点进行特殊处理； ( 3 )在边界(水冷壁)条件的处理上，温度选用了第三类边界条件，把炉内燃烧过程和水冷壁内工质的流动和换热联系了起来，使得水冷壁内的吸热情况对炉内的燃烧和结渣的影响充分体现出来。
