| Abstract: | The basic method to actualize dynamic mesh was introduced in this paper.By using UDF program and dynamic mesh technology,3-D internal flow field of motor with swing nozzle was simulated numerically.It is indicated that dynamic mesh technology can actualize the real-time changing of the calculating area corresponding to nozzle swaying and suits to the calculation of internal flow field for the motor with swing nozzle. |
| Keywords: | dynamic mesh technology solid rocket motor swing nozzle numerical simulation |
