Damping of an oscillatory system with incomplete sealing of the air cavity by magnetic fluid

Abstract

The article presents results of an experimental study on damping an oscillatory system with incomplete sealing of the air cavity by a magnetic fluid. The sealing degree varies due to the process of gas pumping through capillaries of different radii. The proposed relaxation theory of a capillary oscillating gas flow predicts abnormally large values of the damping coefficient and almost complete damping of the oscillatory system with a magneto-fluid inertial element. The obtained data are of applied importance.
