摘要
压力波的传播速度是影响液-固两相流浆体水击压强的主要因素,而波速与管道的材料和流体的成分密切相关。本文分析了含气量对浆体水击的影响,提出了考虑含气量的浆体水击波速公式,在此基础上推导了考虑含气量变化的液-固两相流浆体水击的基本方程。
The propagation speed of pressure wave is a main factor affecting the slurry water hammer pressure of liquidsolid two-phase flow. The wave speed is well related with the pipe material and the fluid composition. In this paper the effects of the air content on the slurry water hammer were analyzed. The formulations of slurry water hammer wave speed, taking the air content into account, were proposed. On those bases, the basic equations of slurry water hammer of liquid-solid two-phase flow considering air content were derived.
