Controll index of run-off loss for porous asphalt mixture;
排水性沥青混合料析漏损失控制指标
Numerical simulation of flow inside voluteand leakage loss show that the flow field with the rings are more uniform and theleakage loss are reduced compared with that without rings.
对风机蜗壳内部流动特征和间隙泄漏情况的研究表明,加装防涡圈后的风机蜗壳内部流场得以改善,泄漏损失大大减少。
