【摘要】 应用紊流三维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－ 讨论了不同布置的水平导流板和竖直导流板的结合使用对气流分布的影响－ 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，发展了边缘气流；支柱空腔内加设竖直导流板抑制了边缘气流的发展，加强了中心气流－ 通过水平导流板和竖直导流板的适当结合，可以实现冷风在格子砖内的均匀分布－更多还原

【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 to find a method used to improve the distribution of cooling air in hot air stove.The influence of differential horizontal plates and vertical 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, that edges gas flow, at the same time, is increased by horizontal plates and that edge gas flow is decreased and circles gas flow in the pillar cavity is increased by vertical plates. It can be achieved by horizontal plates and vertical plates conjoining to make the cooling air uniformly distributed in the hot air stove.更多还原
