Different methods have been applied for the study of insulation layer ablation of SRM, such as theoretical analysis[1], experimental study[2] and numerical simulation[3,8].
Moreover, the rapid development of CFD software has brought great benefits for the development of numerical simulation.
Among all of the general CFD softwares, Fluent has been recognized as one of the most powerful and useful CFD software, and it has been widely used to study the ablation of insulation layer in SRM.
For example, Yu et al[4] performed the numerical simulation of the nozzle and plume flow field.
