A fluid-structure interaction simulation 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 integration process for fluid-structure interaction 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 simulation of a solid propellant grain with inviscid/viscous fluid model. Based on the integrated computed results, flame propagation delay and secondary burning phenomena are examined from the physical and numerical perspectives.OAIID:oai:osos.snu.ac.kr:snu2014-01/104/0000004648/12SEQ:12PERF_CD:SNU2014-01EVAL_ITEM_CD:104USER_ID:0000004648ADJUST_YN:NEMP_ID:A001138DEPT_CD:446CITE_RATE:0FILENAME:고체 로켓 내부 fsbi.pdfDEPT_NM:기계항공공학부CONFIRM:
