摘要

Research towards predicting and quantifying undesirable transient axial combustion instability symptoms in solid rocket motors necessitates a comprehensive numerical model for internal ballistic simulation under dynamic flow and combustion conditions. Once some confidence is gained in a given model's ability to adequately predict such symptoms under a given driving mechanism, or mechanisms if more than one at play, one can turn to modeling various techniques that might be employed toward symptom suppression. In the present investigation, various factors and trends, related to the usage of two sets of inert particles comprised of the same material (aluminum) but at different diameters for the suppression of axial shock wave development, are numerically predicted for a composite-propellant cylindrical-grain motor.
