数值模拟空调柔性风管弯曲工况下的压力损失

摘要

The numerical simulation method is adopted to study the flexible duct of 90 degrees in the condition of right-angle bending in air conditioning system. The results indicated that when the diameter is constant, the inlet velocity impacted strongly on press%采用数值模拟方法,对圆形横截面的空调柔性风管90°弯曲段进行数值模拟,研究结果显示,管径恒定时,入口风速对柔性风管90°弯曲段压力损失影响较大,速度场和压力场的整体变化趋势相同,管径变化时,在模拟边界条件的变化范围内,压力损失趋于稳定值。
