Rigid model for transient flow in pressurized pipe system containing trapped air mass;

水流冲击管道内滞留气团的刚性数学模型

Based on the rigid water column theory, a transient analysis model is developed to simulate the trapped air mass in the long pipeline system with multiple-characteristics.

导出了可模拟分析变特性长输水管道系统内有压水流冲击管道内滞留气团的瞬变流现象的实用刚性数学模型,并通过算例对比分析了该数学模型与现有针对单特性管道的几种简化刚性数学模型的差异,验证了该数学模型的有效性和合理性。
