ABSTRACT

When conducting relief sizing calculations for reactive systems, experimental data is of paramount importance. Experimental techniques for gathering the necessary kinetic data highlighting VSP2 and ARSST testing will be outlined. In addition, the principals behind the system classifications (vapor, gassy and hybrid) will be outlined with example experimental data sets. Relief sizing calculations, and source term considerations for each system will be discussed. Two-phase flow and experimental techniques for determining flow regime (vapor, churn, bubbly or homogeneous flow) will be presented with the goal of providing the audience with a simple comprehensive experimental approach to designing relief systems.
