Abstract

Linear acoustics is adopted to analyze the influence on the entry diameter of the gas inlet orifice on the acoustic damping of the injector. The impedance tube method is used to assess quantitatively damping capacity of entry diameter of the gas inlet in order to find the best structure parameter of the injector. We can draw the conclusion that the acoustic pressure amplitude of the injector entrance can serve as a criterion of the acoustic damping. The entry diameter of gas inlet orifice corresponds to an optimal injector length, but its damping capability remains unchanged.
