Modeling of a Multilayered Propellant Extrusion in Concentric Cylinders
A novel propellant technology requires extruding two formulations with differential burning rates together as a multilayered propellant. This propellant is processed into a concentric cylinder configuration, in the form of slow-fast-slow with single perforation. The material uses different path lengths between the inner and outer sections of the die, both coming from the same pressure driven flow. This study optimizes the die design to enables a wide range of materials, while keeping consistent flow balance. The model recalls to the CFD Module and Heat Transfer Module to study the nonisothermal steady state flow behavior, including viscous heating and heat transfer. The simulations shade light on the interaction between the power law index “n” and the viscous heating in the die design.
