Air Evacuation from the Pressure Accumulator during Work Cycle of the Pneumatic Pulsator

Abstract:

Practically Applicable Vessel Evacuation is Presented in the Article. the Pressure Accumulatoris a Vessel which is a Part of the Pneumatic Pulsator which is Used for Unclogging Outlets of Silos. Apseudo-Schlieren Visualisation Method of Density Gradient and Values of Mach Number are Shown.There is Also a Time Variation of Outflow Velocity Analysed. Airflow Fluctuates after Time of 50 Ms.The Main Reason could Be the Inertia of the Air Mass and a Large Outlet Diameter Relative to the Mainvessel Dimensions
