Estudio Del Fenómeno De Golpe De Ariete En Un Sistema De Refrigeración De Emergencia Con Presencia De Aire.

Abstract

In this paper the effect of presence of air in an emergency cooling system of a nuclear
power plant during the pipelines pressurization stage is analyzed. The pressure waves
propagation along the system pipelines is considered. The presence air in one pipe is analyzed.
A code was developed to simulate the pressure waves propagation in the system. This code uses
the classical method of characteristics (moc) solving the mass and momentum equations. The
two phase homogeneous model was used to represent the two-phase mixture in the pipe with
presence of air. The maximal pressure in each pipe is calculated for the presence of air in one
pipe for the pressurization of the tanks. The influence of the presence of air in the system is
shown.
