Thank you for your very impressive work! Seeing the detailed flow structure really makes you understand why certain developments were made even though it makes conceptual sense. Very excited to see where you'll take this!
The highest performance floor is the egg shaped one, where the small end of the egg is on the leading edge, and the large part towards the rear. This is in line with longboard surfboard design, the so called rearpoint back style is more maneuverable but harder to ride.
you mentioned floor edge - imho the main element is the floor edge wing that increases the outwash from the outer fences even more + the rear cutout & winglet (raised section) that create upwash. Then also there is a cutout on the diffuser side which should ingest the clean "sidepod undercut flow"
I really like this video and would love to see more stuff in category. I think it would help if you had some arrows pointing out the changes your making to the models, I know that your explaining what your doing but there is a lot to unpack from the images and even a few arrows pointing out the areas of interest would help immensely. Im trying to use your videos and kyle's videos as some reference and help with designing my own aero package for a formula category I race in. Big areas of interest to me are underfloor and rear end/diffuser since the cars I race explicitly ban wings but spoilers are allowed, thus trying to find ways to claw back some rear downforce without too big a drag penalty.
The little divots are there to increase the stability of airflow under yaw, something I'm guessing you lack the processing power to investigate properly. Your diffuser is lacking a lot of outwash at the upper trailing edge of the diffuser which increases its performance.
You realize the walls of a vortex are high pressure air, the core of the vortex is low pressure. The two pressures are held in equilibrium by the vorticity, and amount to the static pressure. The rotational flow is a secondary flow that is not in line with the primary streamwise flow. That is because the vortex is a source of drag, it is itself an adverse pressure gradient.
Thats a better way to say it. I really want to make a "why the merc it draggy" video, but need to model it first. Thanks for all you comments, it been the best thing about making these videos, having people.that know way more than I do share their knowledge.
@@nelsonphillips To put it in laymans terms, the vortex under the floor is actually a flow restriction. This is a good thing. For one, it keeps the flow along the venturi walls laminar. It also keeps the pressure in the tunnels low. The lower the pressure in the tunnels, the faster the air is moving. The faster the air is moving, the lower the pressure and the greater the pressure difference above the floor. You notice right aft of the plank area, there's a boatload of turbulence. Well this is because the high speed laminar flow under the car is equalizing in pressure, and the fastest way for air to do this is to turbulently mix. On the wall of the diffuser, the air has at least something to hold on to. There's nothing but empty space in the center, so that air will tend towards turbulence there. That's why the egg shape works well, it turns the turbulence to a vortex. Then the upwash from the vortex can be used to keep the beam wing flow laminar.
Can you design a F1 with a shark fin to stabilise the car and all downforce coming from the floor with ground effect closing the floor and with a fan to produce more downforce and to compare which one is faster, that one or the F1 2022
Pretty sure the car you describe would annihilate a 2022 F1 car. Just the act of adding a fan would improve low speed grip tremendously, which is where you can make up the most lap time.
@@rocketman99 I thought I mentioned that I make all my models. I am still working on speaking clearer though..... The only model I haven't made was the Airshaper vid model.
@@ConnorSmithBirch All the dimensions are from the FIA regulation boxes that constrain these cars. After this its just about applying aero knowledge and test how close your guess was. OnShape because it doesn't make my computer sound like its trying to takeoff.

Enjoy seeing what teams and 'tubers go through in terms of update packages

With the regulations forcing you to make use of implosion vortices, Viktor Shauberger's work is invaluable in order to understand what's going on.

@@nelsonphillips If you want to learn more, check out studies done on the CFD of prolate spheroids.
What CFD software are you using?

great work , your fences are working too hard back down on 3rd and make it sinusoidal
Next iteration I was going to cut it short like RB
@@nelsonphillips btw where did you get the geometry , I also have means so cfd and you mentioned you didnt make the geometry
@@rocketman99 I thought I mentioned that I make all my models. I am still working on speaking clearer though..... The only model I haven't made was the Airshaper vid model.
@@nelsonphillips how do you get the correct dimensions for these and which cad do you use?
