INDUSTRIAL SAFETY ISSUES RELATED TO HIGH VELOCITY DISPERSED TWO-PHASE FLOWS

High velocity dispersed two-phase flows are frequently met in the safety studies of various processes or storage equipment. Storage vessels or chemical reactors, for example, contain liquids at a temperature generally greater than the saturation temperature corresponding to the atmospheric pressure. In case of an accidental or a deliberate release of the fluids they contain, there is a great potential for high velocity flows. Many design aspects of these pieces of equipment as the sizing of venting lines, safe area determination, or in over instances, the impact on man and properties of an accident may require a detailed description of dispersed droplet flows. These flows may among other features involve heat and mass transfer and may host fast chemistry. An example will be given of rather basic and detailed studies of high velocity dispersed flows, aimed at providing more understanding to these challenging engineering design problems.
