Abstract
Shear-induced particle migration is an important issue to be addressed during the processing of concentrated suspensions, which constitute various energetic formulations consisting of polymeric binders with a relatively high concentration of rigid energetic particles. Upon shear-induced particle migration during manufacturing, concentration gradients of the rigid particles are developed that lead to burn rate gradients to alter the overall burn rate behavior of the energetic grains. Here it is demonstrated that changes in the burn rates would occur both in drag and pressure-driven processing flows under conditions in which the particle radius over the gap of the processing geometry is appreciable. Typical results are provided.
