Flow simulation of the shock wave of a dust explosion

Dust explosions are caused by rapid combustion processes in a cloud of fine dust particles. A high heat release occurs, which can cause the gas to spread explosively. The potential danger of dust explosions exists in all industrial plants and rooms in which dust clouds occur and there is the possibility that the particle-air mixture may be ignited by the supply of heat. Dust particles can be made of metal, flour or coal.

MET GmbH analysed the propagation of the shock wave in a room due to a dust explosion and its reflections on the surrounding walls using a time-dependent numerical flow simulation (CFD).

This makes it possible to calculate the time-dependent compressive forces acting on walls or fixtures. The simulation results serve as a basis for the assessment of whether and which safety measures are necessary for the protection of personnel and plant technology.
