Generation of aerodynamic noise by airbag
A model of the velocity potential of small displacements in air flows in relation to pneumatic conveyors is developed. Air flow in a narrow gap between parallel planes is considered as air flow. On the basis of the velocity potential of small displacements, an engineering formula for calculating the noise level arising in the air layer is obtained. The paper considers a fragment of a pneumatic conveyor that uses slotted holes to feed the air layer.
