AI Technical Summary
In the prior art, the traditional axisymmetric lobe mixer of the S-bend nozzle forms a narrow channel between the flow channels, resulting in large flow losses, limited mixing effect, and mismatch between the airflow direction and the flow channel, causing additional aerodynamic performance losses.
A non-circular lobe mixer suitable for S-bend nozzles is designed. By ensuring that the center point of the mixer outlet is consistent with the flow direction of the S-bend nozzle, the peak and trough control curves are generated using the proportional scaling method. The profile is generated using the friction control curve and the sweeping method to ensure that the normal direction of the mixer outlet section is consistent with the nozzle section and that the lobe structure matches the flow channel.
It significantly enhances the mixing effect of the inner and outer bypass airflow, improves mixing efficiency, reduces aerodynamic losses caused by airflow deflection, and makes the flow more uniform, thus reducing flow losses.
