变形压力钢管的压力脉动

On pressure pulsation of the deformable penstock

给出了变形压力钢管压力脉动的偏微分方程，并针对压力钢管一端有压力脉动的情形进行了线性化求解，这对于输液管道的稳定性，特别是对水力机组压力钢管内水体共振现象的分析具有一定的实用性．

The partial differential equations governing the transient flow in the deformable penstock with pressure pulsation are derived. For the case of existence of sinusoidal pressure pulsation at one end of the penstock, the equations have been linearized and solved. It lends itself to the analysis of the stability of pipeline and especially to that of resonance of water body within the penstock of water turbine.
