- A fluid-structure interaction of solid propellant rocket interior is carried out by
employing the ALE (Arbitrary Lagrangian Eulerian) description, a hybrid model of
continuum motion description combining the advantages of classical Lagrangian and
Eulerian description. The fluid-structure interaction process and an automatic re-meshing
algorithm are included to analyze an unsteady fluid-structure interaction phenomenon with
the deformation of solid grain during the simulation. The developed solver is applied for the
full burning simulation of a solid propellant grain, which is a highly-coupled unsteady
phenomenon between gas flow and propellant structure. Based on the integrated computed
results, flow physics in the combustion chamber and the behavior of a solid propellant
deformation are examined.
