摘要

Abstract

The knowledge of two-phase cloud dispersion mechanism from HLG (hazardous liquefied gas) release is the prerequisite for accurate assessment and precise rescue of such accidents. In this paper

an experiment of two-phase cloud dispersion from liquefied CO

hole release is performed. The source terms

such as vapour mass fraction

release velocity and mean droplet diameter

are calculated based on thermodynamic theory. Taking phase transition of CO

droplets to gas into account

CFD (computational fluid dynamics) model for two-phase cloud dispersion is established. The predicted cloud temperatures at the downstream agree well with the experimental data

with the maximum relative error of 5.8% and average relative error of 2.3%. The consequence distances in the downstream direction and in the crosswise direction calculated through two-phase model are larger than those through single-phase model

with the relative differences of 57.8% and 53.6% respectively. CO

concentration calculated by two-phase model is smaller in the vicinity of release hole

and larger beyond 0.135 m downstream. A smaller leakage rate results in a lower CO

concentration and a higher cloud temperature.
