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Ntu " khpi " is the only higher education institution that trains specialists for such important branches of machine - building as turbine construction for atomic, thermoelectric, hydraulic power engineering, heavy electric machine - building, tractor - building, computer control systems for internal combustion engines, boiler - and reactor manufacturing, fat technologies and fat substitutes technologies, tank - building, electrical insulation, cable and condenser engineering
