| Abstract: | In the circulating water system of a thermal power plant or a nuclear power station, there will appear low pressure transient owing to the failure of pump power supply. As the position of the condensers is normally rather high, air release and water column separation in condensers or the pipeline may occur. A mathematical model is developed to calculate the two phase transient flow and has been used in actual calculation. It is suitable for cases where air release and water column separation are taking place in a pipeline and the wave speeds are variable. |
