MODELING OF A GAS LEAKAGE INCLUDING DROPLET TRANSPORT

ABSTRACT Safety assessment of compressed gas storage and pipeline facilities has to consider accidental leaks to the atmosphere. A major concem for modelling of such accidental leaks is the phase change behaviour of the compressed (liquid) gas. The present study assumes that droplets of the liquid gas are present in the gas leak jet. The effect of the droplet concentration and diameter on the behaviour on the jet is studied using Computational Fluid Dynamics (CFD). The impact of these variables on local gas distribution is analysed and discussed
