PHOENICS was used to simulate the venting of chemical reactors. When the maximum permitted pressure of a reactor is exceeded, a safety valve or a rupture disk is opened to discharge the fluid through the ventline. This transient two-phase phenomenon was simplified by making one-dimensional calculations of non-reacting fluids. In order to achieve a good description of the governing processes, new subroutines that describe the interfacial mass, heat and momentum exchange were introduced into PHOENICS. Similarly, a flow pattern map was introduced into the model. The reliability of the proposed model was checked by comparing experimental data on steam/water blowdown experiments with the calculated results performed with the modified PHOENICS.
