| 9. | Abstract : the distribution of cooling air which is in the grille - brick of the inner combustion hot air stove has been simulated with three dimension turbulent mathematical model so as to find a method which is used to improve the distribution of cooling air in hot air stove . the influence of differential horizontal plates on the distribution of cooling air is discussed . the results show that original big circle round field of flow in the pillar - cavity is changed into full one - way field of flow and edges gas flow , at the same time , is increased by horizontal plates . there is a different function with horizontal plates and vertical plates . to make the uniform distribution of cooling air in the hot air stove , it is necessary that horizontal plates and vertical plates are used in a combined way
文摘:应用紊流三维数学模型模拟内燃式热风炉内冷风在格子砖柱中的分布，寻求改善其分布的途径.讨论了加设不同布置的水平导流板对气流分布的影响.模拟结果表明，在支柱空腔内加设水平导流板改变了原有大回旋流场，使回旋流变成大面积的单向流.通过在支柱空腔内加设水平导流板可以发展边缘气流，这恰好与加设竖直导流板的作用相反，水平导流板和竖直导流板的结合使用有望实现冷风在格子砖柱中的均匀分布 |
