WebA steam explosion is an explosion caused by violent boiling or flashing of water or ice into steam, occurring when water or ice is either superheated, rapidly heated by fine hot debris produced within it, or heated by the interaction of molten metals (as in a fuel–coolant interaction, or FCI, of molten nuclear-reactor fuel rods with water in a … WebMar 8, 2004 · Flash-boiling occurs when a fuel is injected to a combustion chamber where the ambient pressure is lower than the saturation pressure of the fuel. It has been known that flashing is a favorable mechanism for atomizing liquid fuels.
WebExisting studies have pointed out that the flash-boiling induced plume-to-plume interaction is related to the change of spray structure, but the detailed process and mechanism are still unclear. In this work, two customized two-hole injectors were used to thoroughly study the plume interaction by using various optical diagnostic techniques. http://journals.ed.ac.uk/ICLASS_Edinburgh/article/download/6047/7894/
