Abstract: Conveying of powders gives rise to hazards to the operational safety of industrial facilities which caused numerous dust explosions in the past. The underlying physical mechanisms are often complex, inter-disciplinary, challenging to observe experimentally, and, thus, not well understood.
To facilitate thorough theoretical analysis we have developed a computational tool whichfocuses specifically on the modeling of processes which may lead to ignition sources. This involves in particular the triboelectric charging of particles and piping components and the formation of deposits on surfaces. The first version of the resulting tool, called pafiX, was recently released for free download on the PTB website.
