A model for erosive burning of homogeneous propellants

We examine the combustion response of a homogeneous solid propellant to an imposed velocity field, as a model for erosive burning. The imposed velocity field has its roots in a multiscale analysis of a planar or cylindrical rocket. We show that for certain realistic choices of the parameters both positive and negative erosion can take place. The underlying mechanism for erosive burning is flame stretch, induced by the imposed velocity field.
