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:應用紊流三維數學模型模擬內燃式熱風爐內冷風在格子磚柱中的分佈，尋求改善其分佈的途徑.討論了加設不同布置的水平導流板對氣流分佈的影響.模擬結果表明，在支柱空腔內加設水平導流板改變了原有大迴旋流場，使迴旋流變成大面積的單向流.通過在支柱空腔內加設水平導流板可以發展邊緣氣流，這恰好與加設豎直導流板的作用相反，水平導流板和豎直導流板的結合使用有望實現冷風在格子磚柱中的均勻分佈 -
