PPT-2019/09/26 Effect of expansion ratio on flame acceleration during hydrogen fueled gas

Jun Yaguchi Wookyung Kim Toshio Mogi and Ritsu Dobashi Department of Chemical System Engineering The University of Tokyo Introduction A precise understanding of the flame turbulence is indispensable to perform an appropriate risk assessment of hydrogen fueled gas explosion. Homogeneous and uniform cosmic expansion . Hubble constant determines scale factor .

A product of combustion accompanied by the creation of gasses and heat is an explosion.. What creates an explosion is the rapid buildup of gas pressure. Detonation occurs so rapidly that oxygen in the air cannot participate in the reaction. Leaving it that many explosions have their own source of oxygen.. Planning as Satisfiability. Clause Learning.
