| Abstract: | This paper presents the analysis on the 2-D transient temperature field and stress field of compound nozzle by use of the finite element method.While making temperature field analysis the grid deforming method has been used to consider the ablation moving boundary and to eliminate temperature osilation due to large temperature gradient efficiently.The numerical example has shown that the method provided in the paper is simple and reliable.It is easy in engineering practice. |
