| Abstract: | The thermo-structure computation procedure of nozzle in SRM(solid rocket motor) was embedded in software FLUENT based on user-defined function (UDF). It realized coupled heat transfer data picked using UDF macro commands.Contact boundary identify procedure was complied and direct constraint method was applied to solve boundary nonlinear problem.Then it achieved thermo-structure integrative computation for nozzle in SRM. |
