Abstract:

The objective of the project is to develop a computer code capable of predicting single and two phase hydrodynamic behavior of fire suppressant fluids during transport through piping systems. This new code will be able to predict pressure losses and flow rates for a wide variety of fluids, through piping systems with various combinations of fittings, over a broad range of pressure and composition conditions. The code will also be able to predict transient behavior for start and stop of flows, as well as for time varying pressure heads. A key technical approach in the present program is utilization of advancements made in other applications that deal with multiphase flows. In particular, the highly sophisticated computer codes that have been developed for thermal hydraulic analysis of nuclear power systems have all the characteristics required for analysis of fire suppressant systems. Several relevant codes were reviewed and RELAP5 MOD3, Version 3.2 was selected as the base code for the present work.
