摘要
利用实验和数值模拟方法,对90°弯管阻力系数进行了研究,分析了管道中的压力分布和速度分布,探讨了空气通过局部构件产生阻力损失的变化规律和机理,测量了局部构件对上下游管段的影响长度,找出了对单个局部构件阻力损失机理和变化规律。
The resistance coefficient of 90° bend pipe is studied and the pressure and speed distribution in pipe are analyzed by using the experiment and numerical simulation method. The resistance loss mechanism and change rule of single local component is found out by discussing the change rule and mechanism of resistance loss and measuring the effect length caused by local component.
