Hello Everyone,

This Thread is mainly for your aerodynamic learning pleasure!!! Me and a number of other F1Technical members have teamed up to create Geometries and then analyze their aerodynamic characteristics.

Please all feel free to contact me either via email or by posting on the thread if you want your own CAD model run in CFD, or if you have any questions about the models shown.

My Email: CFD@Play101.fsnet.co.uk MSN:Rascal1001@Hotmail.com

In order to try and prevent overloading of the thread with pictures, all the pictures in the thread are being grouped and links will be posted for each model that CFD has been used on, so if pictures you seen at previous visits are not here, try the links The links will be posted below. Please continue to post in this thread with any questions or comment you may have.

Enjoy!!!!

Rear Wing Model 1 (Alero)


USA SCCR Race Car - New

[/url]

what is new for 2010 for front and rear wing

[quattro]

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,

quattro

What about slots on the end plate like viewtopic.php?f=6&t=6608&start=75

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

[quattro]

thanks, i will check that out!

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.









regards,

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.

What programs do you people use to make these F1 models?

[PNSD]

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?

[jian]

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

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.

What is the CFD software that you guys use?

[Tonn]

I am useing CFDesingn
Does anybody know how do turn off the Auto Stop?
I just keep geting that message: Time Average Values have flattened - Auto Stop

[ChrisTipper]

Can I ask do all the F1 teams use CFD?

[n_anirudh]

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

[pottsymouthy]

Has anyone got any f1 cad models that they don't mind sending to me? So I can start to mess around with them.

I am learning how to use CFD but need some CAD models to use.

Cheers for any help.
