Description
Summary:The Finite Element Method has been widely employed in engineering and physical sciences due to its huge applicability that resulted in commercial software used for both industries and academic researches. Recently, those software were improved to simulate moving boundary problems, like phase change and mechanical erosion, which is a common physical process in ablation problems. The ABAQUS software affords a subroutine called UMESHMOTION, which is combined with Arbitrary Lagrangian–Eulerian Mesh to allow modeling heat-transfer with ablation. However, the subroutine must be adapted to the particular modeling for this problem. In the present work, a subroutine code was developed to investigate ablation of a material; the results were compared with results obtained from a different numerical approach, and the physical model is validated with data extracted from an experimental test case. The results obtained were physically coherent with the proposed model, and the methodology developed allows it to be used in future ablation engineering problems including nozzle thermo-structural analysis.
