Hello everybody,

i designed and analysed my own rear wing and i have now some problems with the end plates. they create hard vortexes on their upper side and i'm thinking now about how to reduce these vortexes.


you can see pictures here:

Maybe you can give me some ideas how to improve my design?

Kind regards,

What about slots on the end plate like http://www.f1technical.net/forum/viewtopic.php?f=6&t=6608&start=75

Also maybe the shape of the end plate behind the wing...

Hey there guys!

I'm currently building a Formula Vee car here in South Africa. It's a really competitive series with all the cars locally designed and built by guys in their garages. Check out http://www.formulaveesa.org.za to find out more.

I've been designing the car in Pro-E for the last 2 years or so and have finally started construction, with the chassis nearly complete. However, I've never had a chance to run the car through CFD.

Would anyone be interested in running it? would be quite cool to be able to compare theory and practice as it's a real car that will compete in a national championship, and changes etc... can be measure in the real world.

they are hard to get rid of, even with the slots. In fact i don't know if the slot enhances them or cancels them.

you can try cutting the ends like how i have mine.
I also have gurneys on the edges like on the F10 ferrari. They cause that vertical blue area right behind the endplate.
I also made sure the element trailing edge met with the upper edge of the endplat and the cut out somewhat followed the curvature of the wing. In fact the wing profile is something i also put a lot of effort into carefully copying from pictures and correlating with the regulations.
Imitation reveals the little tricks. :)
For Sure!!

Hello.

I was wondering if somebody could offer me some help with Fluent.

Ive done a 3d sim, I simply want to display the pathlines as shown here:
http://www.f1technical.net/articles/71

I know that I have to define where to release from but thats where I get stuck.

Say for example my flow domain is:

x = 10
y = 2
z= 4

And then say my object of interest is at:

x = 4 to 6
y = 0.75 to 1.25
z = 1 to 3

How would I go about setting my pathlines using such dimensions as an example. Is this clear?

Thankyou :)

Would you try to design how the Turbo F1 2013 will look?

Hi I'm new here and I've just discovered this forum, I registered :lol:

Now I would like to know more about the famous f-duct first invented by the Mclaren this year, has anyone got reliable information ? If so, mind to share please?

Because I've googled for it a while now, & I don't get quite useful details about f-duct.

Yes, most do...esp Renault...who have a very aggressive aero program.
