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

Abstract

abstractEN: 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.score: 7collation: 327-33
