Numerical simulation of gas explosions in linked vessels

The ability of the CFD code AutoReaGas to simulate a gas explosion in two l inked vessels was investigated. These explosions present an anomalous destr uctive power because both peak pressures and rates of pressure rise are muc h higher than those generated in single vessel explosions. A fair agreement was observed between the computed results and experimental data taken from literature. Moreover, the computed values of the turbulence intensity at v arying diameters of the connecting pipe demonstrate that turbulence induced in both vessels represent a major factor affecting the explosion violence.
