Impact on blockage of an airflow containing solid particles

Experimental results are presented for the impact on blockage by airflow exhausted from a highpressure vessel and containing micron-sized solid particles. The static and the dynamic pressures on the blockage at different initial jet parameters are determined. The degree of the pressure increase on the blockage depending on the initial pressure in the vessel and the solid phase concentration is determined. The pressure of the flow with the powder on the blockage may be up to three times as much as the same in pure gas.
