The depressurization of a vessel containing saturated or subcooled liquid may occur in a variety of industrial processes and often poses a potentially hazardous situation. A numerical model was developed for estimating the thermodynamic and the dynamic state of the boiling liquid during a boiling liquid vapor explosion (BLEVE) event. The model allows calculation of bubble nucleation and growth ...

Studies have shown that when assessing safety conditions, it is possible to use methods for calculating the consequences of exposure damaging factors fire and explosion: thermal radiation a strait fire; effects combustion products vapor-air cloud in event flash shock wave during cloud; fireball. At same time, additional research required order adjust regulatory framework field safety.

Preventing unexpected explosive attacks and tracing explosion-related molecules require the development of highly sensitive gas-vapor detection systems. For that purpose, a micromechanical cantilever-based olfactory sensing system including a sample preconcentrator was developed to detect 2,4-dinitrotoluene (2,4-DNT), which is a well-known by-product of the explosive molecule trinitrotoluene (T...

An explosion occurred at a polyvinyl chloride (PVC) resin manufacturing plant. The explosion originated at an atmospheric storage vessel when it received a slurry discharge from a suspension polymerization reactor. The pressure rise caused by the uncontrolled flashing of superheated liquid vinyl chloride resulted in the complete separation of the roof from the tank shell. A cloud of vinyl chlor...

One of the possible consequences a severe accident at nuclear power plant with pressurized water reactor is steam explosion that occurs as result interaction high-temperature melt core materials and can lead to failure containment. The paper considers initial stage (premixing water) under stratified geometry. key phenomenon leading premixing dynamic effect collapsing vapor bubble in liquid on s...
