Experimental Study Of The Efficiency Of Damping Resonant Oscillations In A Liquid By Adding Gas

Abstract

Standing waves can form in the hydraulic systems of various devices. When the frequency of the input energy approaches the natural frequency of the hydraulic path, resonant oscillations occur. Such fluctuations can adversely affect the operation of hydraulic systems. The search for effective methods for damping resonant vibrations that occur in hydraulic systems is an urgent task of scientific research. The authors proposed a method for damping resonant oscillations in a liquid by supplying gas to an acoustic circuit. The article presents the results of an experimental determination of the efficiency of damping resonant vibrations in a pipe by adding different gases under different modes of fluid motion. The results of theoretical calculations are well confirmed by experimental data.
