Stuff like this is what differentiates an engineering company from a bodykit company. Dabbled with these concepts in college motorsports, kinda hate that i can't unsee what it takes to do it right, but inspires confidence seeing companies talk the talk. (Solidworks) Streamlines look cool, but mesh quality, yaw, convergence with the tunnel, tire squirt, radiator conditions, etc. is how real functional aero packages are developed.

Awesome discussion. Love all the detail about how you guys have correlated your CFD. One of the things I’m curious about is how you correlate the flow under the car assuming the wind tunnel you guys used doesn’t have a rolling floor. Seems like the behavior of the air against the ground would be super different in the wind tunnel vs on track. I’ve read some wind tunnel reports (without rolling floor) that seem to potentially underestimate the effect of diffusers as a result. Maybe something you could cover in a future video.
@VerusEngineering2 ай бұрын
In our simulations, we simulate rolling road and the wheels spinning with various boundary condition settings. Within our abilities, we simulate real world behaviors as closely as possible to ensure our simulations match real world conditions. Agreed, non-rolling road wind tunnels are less than ideal with estimating anything ground effects related. As such, anyone claiming or trying to extrapolate data from ground effects when the vehicle is on a non-rolling road with the wheels not spinning, results should be taken with a grain of salt.

@rolandotillit28673 ай бұрын
When you start with better shapes, that are less prone to separation, or detached flow, it also helps your CFD because CFD is not fantastic at predicting unsteady flow, or turbulence transition without a lot of computer power. This is one of the benefits of having a good wind tunnel, where you can validate geometries that tend to have less separation, which in turn will give more accurate CFD results, in a virtuous feedback loop.

Would love some more insight on the mounting of the UCW rear wing on the gen 2 BRZ using rivnuts. What kind of strength analysis / testing was done? What's the expected fatigue behavior after 100+ hours on track? 500+ hours? What other options were considered?
@VerusEngineering2 ай бұрын
We do not foresee there ever being any fatigue issues with this wing. We have had people stand on top of the wing without issue and we have a test pilot program where 8 drivers did plenty of testing for us and there was never a single issue regarding strength. This mounting solution is plenty strong but does make for a bit of a difficult install. We plan to revisit the mounting in the near future.

Would love to know if you have a target lap timeline improvement or downforce number when you set out to design a package for a platform.
@VerusEngineering3 ай бұрын
Lap time decreases are subjective as every track is different, but we do typically have an idea of what downforces numbers we would like to achieve before starting the design process.

To be 100% honest, we do not have any plans for 350/370 development. We tried to get into the market back in the day, but it fell flat, so it didn't make sense for us to look into them any further.

If you can share, how do you handle your tire contact patch geometry in your CFD model? The contact patch and tire squirt tend to be very numerically sensitive, especially in RANS. I'm always curious how different aero groups handle this area.
@VerusEngineering3 ай бұрын
We have a specific amount of "flat spot" for the tire that we have used for years. This allows us to simulate the contact patch of a tire in real life, in CFD.

@@VerusEngineering Makes sense. I'm assuming you must extrude it a little bit so that your mesh skewness in the gap between the tire and the ground plane isn't bad?

When doing yaw CFD, the half a car approach isn't bad, because the windward side of the car during yaw is the one most sensitive to disturbance, both from the tire wake, and vortex breakdown and the resulting recirculation that causes. The leeward side has everything working for it from a downforce perspective. Car is lower to the ground due to roll, the wake is moving away from the underfloor. So improving the windward side tends to yield better results in yaw, especially in a competitive environment, plus it saves computation since you're only doing half the car.

Well said. We certainly appreciate the response.
@jkrzeminski2 ай бұрын
Why do you think the leeward side of the car is lower than the windward side during yaw?
@rolandotillit28672 ай бұрын
@jkrzeminski because when you turn the car, it rolls, the side facing the corner, the windward side, lifts up, while the leeward side, drops down.
