Hydrogen gas explosions in pipelines, modeling and experimental investigations
Knudsen, Vegeir (Doctoral thesis; Peer reviewed, 2006)Gas explosions in closed pipes with a single obstacle have been investigated both numerically and experimentally. Most of the work is related to hydrogen and air mixtures, but other fuels have also been used. At the present ... -
Simulation of flame acceleration and DDT in H-2-air mixture with a flux limiter centered method
Vågsæther, Knut; Knudsen, Vegeir; Bjerketvedt, Dag (Journal article; Peer reviewed, 2007)Flame acceleration and deflagration to detonation transition (DDT) is simulated with a numerical code based on a flux limiter centered method for hyperbolic differential equations. The energy source term is calculated by ...
