| Abstract: | 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. |
