SCALE MODELING OF GAS-EXPLOSIONS IN CLOSED VESSELS

The effect of geometrical dimensions on combustion of gas mixtures in closed vessels with obstacles has been studied. We show the possibilit y of considering separately the effects of combustion intensification with allowance for flame self-turbulization and the interaction of fla me with obstacles. It has been established that the degree of combusti on intensification due to self-turbulization is a universal function o f the vessel volume and of the physicochemical characteristics of a ga s mixture and is controlled by the Froude and Lewis numbers. Scale mod eling of the interaction of flame with obstacles is shown to be possib le.
