- •
A new alternating-lobe nozzle and two types of lobe-peak spoilers are introduced.
- •
The distribution of the primary stream in the jet mixing flow field is obtained.
- •
The jet mixing flow field is divided into several regions for analysis.
- •
The division of the streamwise vortices into segments is propounded.
- •
Mechanisms for the high mixing effectiveness of lobed nozzles are analysed.
