Parallel Computing of Jet Impingement During Ignition Transient Using Fluid-structure Interaction

Loosely coupled approach is used and fluid-structure interaction analysis has been developed using computational fluid dynamics (CFD) software Fluent and computational structure dynamics (CSD) software Abaqus by MpCCI (Mesh-based parallel Code Coupling Interface). Pressure results from the CFD solution are interpolated and applied as pressure boundary conditions on the structural model. Displacements from the structural analysis are interpolated and applied to the boundary of the CFD mesh. A User Defined Function (UDF) is written by C language to simulate the propellant burning process by adding source term and setting the burning rate law. A viscoelastic behavior of the propellant is modeled by means of relaxation data in prony series and performed in Abaqus. The simulation efficiency is proved. The results show that the deformation and the flow are tightly coupled during ignition transient, and the main cause of this deformation is the pressure difference between the head-end and the aftend of the motor.
