摘要
采用CFD技术对通风笼的机械通风过程进行仿真,并对普通U型风道进行优化。结果表明:小u型风道提高了通风的均匀性、有利于消除通风死区且降低了能量损失;另外,间歇通风比连续通风更节能,是一种可行的实际操作方式。
The course of mechanical ventilation for overground ventilated path was simulated by CFD,and the ＂U＂ ventilated path was optimal designed.The study indicated： The improved ＂u＂ ventilated path improved the ventilated auniformity,was advantageous for eliminating the dead area and reducing the energy losing.In addition,intermittent ventilation economized the energy＇s use,was a feasible operation.
