* fichier : pressuhx2.dgibi * * Containment pressurization (Phebus size) with heat losses. * 3D mesh of a 14.5 m3 cylindrical containment with a 10cm in depth vertical wall. * * Initial pressure and temperature are 1bar and 40oC with the wall at 60oC. * Steam is injected at a constant 50g/s mass flow rate and a temperature of 150oC. * * Transient is computed for 1000s. We check the condensation mass flow * rate evolution (that starts at about 20s). * * Compare to pressu.dgibi, hereafter heat losses are considered : the * containment is in contact with air or water. The water table elevation * is moving with time ; the convective heat transfer coefficient is * computed by the Mc Adams correlation (by use of a personnel procedur) ; * air and water characteristic lenght and temperature are known with * time for both. * * Auteurs : E.
