| Popis: |
The prototyping and testing of a supersonic cruise nozzle that covers wide range of nozzle geometry configurations (to help with large operating envelop of an aircraft) is both time consuming and expensive. Numerical simulations offer quick and less expensive solution to reduce the design time and cost. In the present study one of the configurations of a supersonic cruise nozzle is simulated for a range of nozzle pressure ratios and the results are compared with experimental data. The pressure-based and density-based solvers in ANSYS Fluent CFD code are used for the validation study and solution based adaption is examined to determine if the accuracy can be improved by local mesh refinement. The simulation results show very good agreement with the experimental data, and this study demonstrates an optimized simulation process which can be used to study the entire envelope of flow and nozzle geometry conditions. |
