Burn-back Analysis Program Development of a Solid Propellant Motor using Fast Marching Method

The Fast Marching Method (FMM) is a widely used algorithm for analyzing burn-back tendency, which can reduce computational complexity of the typically used algorithms, such as level set method (LSM).The purpose of this study is to develop and verify a burn-back analysis program using FMM.Burn-back analysis was conducted on various two-dimensional grain configurations and results were compared with a program based on LSM.It was confirmed that both LSM and FMM programs achieved highly accurate solutions compared to the analytical solution.It was also found that the computational time of the FMM based program was reduced compared to that of the program based on LSM.
