Abstract

Abstract This contribution aims at systematically determining the extent of classified areas in two-phase releases of pure components. To this end, a novel algorithm is proposed to ensure all proper steps are taken towards accurately computing the required properties of the resulting cloud. The intended framework is based on a refined one-dimensional dispersion model that accommodates (i) the influence of the vapor component on the energy balance of the two-phase jet model, (ii) new decay constants to calculate velocity, concentration, and temperature profiles, (iii) a new normalization ratio to compute the temperature along the centerline, and (iv) a new correlation for the entrainment coefficient in the two-phase region. Altogether, these modifications produced results that are in very good agreement with (scarce) experimental data available in the literature. The hope is that this simple algorithm can predict within reasonable precision the reach of the hazardous cloud in open field situations.
