Modellrechnungen zu Explosionen freier Gaswolken von Kohlenwasserstoff/Luft‐Gemischen

Model calculations on the explosion of free gas clouds containing mixtures of hydrocarbons and air. The procedure presented permits a description of continuously and discontinuously accelerated explosions. The explosions considered are deflagrations, i. e. combustion-supported compression waves. It is possible to calculate, for a given rate of propagation of a flame front or the motion of a piston assigned in a model, the corresponding flow field (compression wave). The corresponding pressure, density, and velocity distributions can be utilized for safety considerations. Application of the results requires that the simulated acceleration processes can be transformed into real events. With the experimental results presently available this is possible only in very crude fashion and can serve only as a rough preliminary guide.
