| This thesis presents a numerical method for determining emergency relief requirements for a top-vented cylindrical vessel equipped with an ideal nozzle. The fluid systems under consideration must be tempered and contain either one or two components. An interface between a spreadsheet application and a CAPE OPEN compliant thermodynamic package was developed. Fluids exhibiting partial disengagement with either churn-turbulent or bubbly flow behavior were considered. A vessel condition subjected to energy input from an uncontrolled external source such as fire was considered with no chemical reaction. The emergency relief calculations are based on the DIERS recommended homogeneous equilibrium model. The calculations are presented with examples along with comparisons with simplified analytical short cut solutions available in the literature and more rigorous calculation methods. |
