Analysis of ventilation systems subjected to explosive transients: far-field analysis

Abstract

This report outlines progress in developing a far-field explosion simulation computer code. The term far-field implies that this computer code is suitable for modeling explosive transients in ventilation systems that are far removed from the explosive event and are rather insensitive to the particular characteristics of the exp 1 os i ve event. This type of analysis is useful when little detailed information is available and the explosive event is described parametrically. The code retains all the features of the TVENT code and allows completely compressible flow with inertia and choking effects. Problems that illustrate the capabilities and limitations of the code are described.
