Abstract

The rheological characterization platforms for the extrudability and safety analysis of energetic materials were investigated. The basic mechanisms of wall slip and deformation occuring during the viscometric flows of energetic suspensions, which are generally fluids that exhibit a yield stress and apparent slip at the wall were outlined. The apparent slip layer is defined and its thickness is a fraction of the particle diameter. For energetic suspensions, the flow curves need to be collected as a function of the surface to volume ratio of the viscometer employed and the wall slip velocity values should be used to correct the shear rate at the wall. The yield stress value of energetic suspension was determined as a byproduct of the wall slip analysis.
