| Abstract: | Based on the two - phase transient flow in the downstream tunnel system of spare turbo generator set of Lijia Xia difference equation of characteristics is applied to deal with this transient flow. In this paper, we analyse the water hammer pressures in the upstream conduit and downstream tunnel of the turbo - generator set and the stability of the turbine speed.The effect range of interface surging have been given in this paper. |
