Abstract
As a hybrid of continuum motion description which combines the advantages of classical kinematical descriptions, i.e. Lagangian and Eulerian description, the ALE (Arbitrary Lagrangian Eulerian) description is adopted for the simulation of a fluid-structure interaction of solid propellant rocket interior. The fluid-structure interaction phenomenon with the deformation of solid domain during the simulation. The developed solver is applied for the ignition simulation of a solid propellant grain, which is an unsteady highly-coupled phenomenon between gas flow and propellant structure. The computed results show complex flow physics in the combustion chamber and the behavior of a solid propellant deformation.
