Visualization of aluminum dust flame propagation in two different lengths prototypes: some experimental considerations
Résumé
Dust explosion is a major hazard for all industries dealing with powders, as all fine flammable dusts can cause an explosion when dispersed. These industries have to predict the consequences of potential explosions in given scenarios. To predict dust explosion consequences, models commonly used for gas explosions can be adapted. Although these models can be adaptable for organic dust explosions they are not accurate enough in case of metallic dusts [1]. Experimental studies are necessary to understand flame propagation mechanisms for these metallic dusts. Aluminum dust flame propagation is studied inside two prototypes of different lengths.
