![]() Getting better at this. I should be able to do a full simulation with rotating wheels pretty soon.  |

It there was no dirty air in the next lane than is this accurate? As a real life tunnel seemed to demonstrate that there was. Also, I don't see that the wheels are canted at all. It would be easier to modify the car on the computer model I would think. I have not voted yet...I am on the fence. You continue to impress!

Am I reading the legend correctly? The orange colored arrows are indicating travel at between 947 and 1200 in/s? That's like 53-68 mph?

Good catch, that should have been 960 feet per minute or 15 feet per second. I will correct. The CFD at correct air speed is showing the dirty air in the adjacent lane now. I will post later |

If you've got a way to hit even 20 mph without external augmentation, We're all ears over here! lol

I calculated theoretical maximum to about 16.6 ft/s or 11.3 mph. One good thing is the I was able to model drag force successfully.

I may have to change the banner of this forum to "The Finest PWD Porn on the Internet".

Hey there, Looking good. Interesting about the dead spot on the front wheel. Things to take into consideration:
1. The Front of the car will be narrowed so that the DFW is contacting the rail while the rear's are centered as the car is going down the track.
2. The wheelbase looks too long in the model. Most are between 4.5"-5" in front of the rear wheels.
3. I see the Toe on the DFW, but not the negative cant.
4. The front of the car would be tapered to a smaller point not kept at the .25"thick.
The Positive cant on the rear's looks good! I just had an aerospace guy in. He was saying it is hard to get accurate computer models for Drag. He works with airplanes and said that calculating lift works well, but difficult with drag. Do you have thoughts on that? I have no idea...this is all out of my league.
