A Systematic Algorithm to Compute Hazardous Area Extent for Two-Phase Releases Based on an Improved Low-Dimensional (Simple) Dispersion Model
Abstract
This contribution aims at systematically determining the extent of classifi ed areas in two-phase releases of pure components.
To this end, a novel algorithm is proposed to ensure all proper steps are taken toward accurately computing the required
properties of the resulting cloud. The intended framework is based on a refi ned one-dimensional dispersion model that accommodates
(1) the infl uence of the vapor component on the energy balance of the two-phase jet model; (2) new decay constants
to calculate velocity, concentration, and temperature profi les; (3) a new normalization ratio to compute the temperature along
the centerline; and (4) a new correlation for the entrainment coeffi cient in the two-phase region. It was found that the entrainment
coeffi cient (
