Resumo
In order to predict the consequences of an accidental explosion in a chemical plant, dedicated computational codes are applied. Stokes is a code that has been developed at UNICAMP to simulate explosions in confined areas. Comparing with experimental data, the original code showed great agreement with its parameters SF as 0.16 and CC1 1.5. Aimig to improve the combustion model, by reducing the level of empiricism, the code has been modified. The use of the Kolmogorov length scale leads to extinction of the flame and the use of the fractal approach resulted in its faster propagation.
