文摘
- •
Propeller suction on the flow is observed upstream to a distance of 1 prop radius.
- •
Blade induced velocity fluctuations extends upstream to 0.4 prop radius.
- •
Prop reduces the detached volume size but don't remove totally the flow separation.
- •
The flow separation boundary is identified by the velocity skewness coefficient.
- •
The "mode" wake is a more robust description of the propeller inflow.
