Dust lifting behind a shock wave. Analysis based on the E-E method
Abstract：The E-E method was used to study the lifting of dust behind a shock wave. The in- fluence of gas velocity, dust density, and particle diameter on the lifting of dust was studied. The results show efficient lifting of dust when a low gas velocity (100 to 300 m/s) existed be- fore the shock wave. Dust density, 1 000 or 3 000 kg/ma , had little effect on lifting of the dust. Particle size had a significant effect on dust lifting. Dust particles with a diameter above 0. i mm suppress lifting of dust. Finer dusts are lifted efficiently and the resulting dust cloud is more uniform. These results can guide methods for preventing secondary dust explosions after initial gas explosions.
