title = "Particle damping characteristics of low and medium frequency oscillation in solid rocket motor",
abstract = "Except for high frequency (>1000Hz) combustion instability, nonlinear combustion instability in the low and medium frequency (100-1000Hz) has been observed in solid rocket motor (SRM) in recent years. In this paper, particle damping characteristics of the low and medium frequency oscillation are analyzed in SRM. Particle damping is highly dependent on the particle size distribution of the condensed combustion products of propellant in the SRM, which is actually affected by the operating pressure and the initial aluminum particle size in the propellant. In order to determine the particle size distribution of the condensed combustion products, using three propellant samples with different initial aluminum particle sizes, the collecting experiments are carried out under different operating pressure (3-7 MPa). Particle damping of the condensed combustion products is calculated with the distribution of particle size as input using the method modified by Culick. The effects of different operating pressure and initial aluminum particle sizes on the particle damping are analyzed in the frequency range of 100-1000Hz.",
