摘要

This paper is devoted to the analysis of the jet trajectories,obtained using computational fluid dynamics(GFD),at two different scales(laboratory and industrial)with application to quenching of runaway reactions.One of the goals was to describe how the jet penetrates the fluid in the stirred vessel and to build an easy to use correlation for research and industrial purposes.A model of the jet trajectory based on the analogy with a jet in a cross-flow has been used to predict the jet trajectory at the pilot and industrial scales.The correlation,built using a statistical analysis,has shown that the jet in a cross-flow model performs very well to describe the jet trajectories.A very interesting conclusion is that the correlation constants were found to be independent of scale.Finally,the authors proposed a definition of the penetration depth and use it in its dimensionless form to predict how the jet penetrates in the industrial vessel with the current injection conditions.
