Vapor film formation and growth due to contact of a hot body and other liquids arise in some industrial applications including nuclear fuel rods, foundry and production of paper. The possibility of a steam explosion remains in most of these cases which could result in injuries and financial damage. Due to the importance of such phenomenon, this study deals with vapor layer forming, growth, and ...

severe accidents of process industries in iran have increased significantly in recent decade. this study quantitatively analyzes the hazards of severe accidents imposed on people, equipment and building by a hydrogen production facility. a hazard identification method was applied. then a consequence simulation was carried out using phast 6.54 software package and at the end, consequence evaluat...

The present paper reports on the experimental and theoretical investigations on the lower explosion limits of single dusts, gases as well of two phase mixtures such as gas/dust, vapor/dust, spray/vapor and vapor/gas. The materials used were corn starch, lycopodium, toner and high density polyethylene as dusts, methane and hydrogen as combustible (perfect) gases and acetone and isopropanol as sp...

The characteristics of cavitation and atomization induced by underwater explosion near a free surface have been investigated the multiphase fluid model based on two-fluid phase transition. This numerical method can provide transition between liquid its vapor phases during shock wave rarefaction propagation at any time in explosion. detailed density, pressure, vapor, volume fraction contours zon...

Due to the flammability and explosion characteristics of the propane vapor cloud, a nearby propane tank farm could possibly present a significant risk to the operation of nuclear power plants. Accidental releases of propane may occur in the propane supply pipeline, at the propane storage tanks, or on the propane transportation routes due to propane transport trailer truck accidents. Loss of con...
