Large scale dust explosions in linked enclosed vessels
conference paper
TNO participated in the DESC project (Dust Explosion Simulation Code) which was supported by the European Union. The aim of this project was to obtain a numerical model (CFD-code) to simulate dust explosions for complex geometries, like industrial facilities. To be able to validate this model, TNO performed large scale dust explosions in linked enclosed vessels. Two I m3 explosion vessels were connected with pipes of various lengths and with or without a bend. Dust explosions with Potato Starch, Coal and Silicon powder were performed to determine, beside the pipe configuration, the influence of the ignition location, the presence of obstacles, and pressure relief by venting one of the vessels. These determinations resulted in a very useful data-set for validating the CFD-code. Although these experiments were not meant to fully understand all the observed phenomena, some explanations for observations were given.
