For measuring the mean flowrate of pulsating gas flow, dampingchamber is set between the pulsating source and the flowmeter to damp the pulsating effects.
Strong damping effects are possible because of solid particles in the chamber.
燃烧室内的固体颗粒可能引起强烈的阻尼效应。

A study on the influence of structures and parameters of the chamber on pressure ripple damping is carried out and a method for determining the best structure is also offered.
