Accidental releases of pressure liquefied materials may result in instantaneously vaporising, or flashing, jets which mix with ambient air and disperse. In consequence modelling, it is important to correctly describe the initial jet behaviour as this can influence the subsequent vapour dispersion. Numerous techniques are available for modelling flashing jets and their dispersion and Computational Fluid Dynamics (CFD) is a tool that is becoming more widely used. Confidence in model predictions can be gained by comparing them with experimental data as well as with other models. This paper describes the CFD modelling of a small-scale flashing propane jet and comparison with both experimental data and integral model predictions.
