Diffuser design on F1 undertrays
Diffuser design on F1 undertrays
(OP)
At the Melbourne Motorshow I noticed that all three of the diffusers on display had curved triangular fins. Are these supposed to initiate the main trailing vortices, or do they have a more mundane purpose- like restricting sideways flow?

RE: Diffuser design on F1 undertrays
The underbody tunnels have large vortices feeding the flow under the car. Those vanes you seem to enhance this effect and are developed experimentally.
I haven't seen any flow visualisations nor lift coefficient results with or without these vanes. Can't help any more than that.
