Propagation of explosive gas clouds in the vicinity of chemical plant . The propagation of large amounts of gases in the vicinity of industrial plant can lead to safety risks and must therefore be estimable in their effect. Methods of both theoretical and experimental simulation are available. Among the computational models, the conventional propagation models used in meteorology are suitable for free propagation. In cases of propagation close to buildings, the relatively straightforwardly applied binomial model is a better choice. Owing to the occurrence of turbulence, the calculations should be supported by wind tunnel studies. An unfavourable system leading to accumulation of large amounts of gas is seen to be a U‐shaped arrangement of buildings with incident flow on the convex side.
