| 英文摘要: |
| In order to calculate the combined flow field of inlet and fan，an improved divided actuator disk model was established on
the basis of the original actuator disk model theory. By comparing the numerical simulation method with the original model, the accuracy of
the divided actuator disk model relative to the original actuator disk model was verified. By using the divided actuator disk model to model
the compressor partially, the numerical simulation of the combined flow field of the inlet/fan including the divided actuator disk model was
analyzed. The results show that the divided actuator disk model can effectively eliminate the error caused by the hypothesis of the actuator
disk model, and the numerical simulation results are closer to the full 3D simulation results, which provides a feasible and accurate method
for the numerical simulation of the integrated inlet and engine combined flow field. |
