    TLDR: they probably used a smooth ground belt for more consistent and less wear-dependent simulation data because of their limited number of tests but underestimated the ground boundary layer and its effect on the ground effect cars caused by a rougher, more realistic road surface.

      ​@@Bahamuttiamat this is a pretty bad take in my opinion for a couple of reasons
      A. While i know which 08 Renault win you're talking about you failed to mention the fact that he won 2 races with that car, the second of which being on merit and not controversial at all
      B. Even if the 15-17 Mclaren was the 5th fastest car (which they certainly were not anywhere close to) it really wouldn't have mattered as they broke down every other race
      You also decided to skip over his whole Ferrari stretch which is the one part of his career everyone praises him for outdriving his car, yes ofcourse no one can win a championship with the worst car on the grid, but as Fernando showed in 2012 you can get extremely close to one with the 3rd or maybe even 4th fastest car if you have the tallent to do so
      in the end i agree that you need a good car to succed in f1 but jeash pick a different argument than "Fernando couldn't win in the Mclaren Honda"

    I want to thank Willem for turning up and explaining this stuff to us. For years I used to read magazines like Autosport and wonder about how teams either moved forwards or back in performance, and study the differences between aero on the photos of races. It always fascinated me, but of course I was basically just trying to guess.
    So I greatly appreciate this level of explanation. It truly puzzled me how Mercedes not just dropped the ball in their design but took so long to fix it. This explains an awful lot.

  • @wnoyes1100

    So Ground Effect era significantly altered how critical the surface texture of the track is to performance. Restricted wind tunnel tests for Mercedes combined with a test “road” surface that was too smooth meant their testing failed to demonstrate real world performance. Consequently, Mercedes spent a long time in the dark as to why their cars were performing so badly compared to their own expectations.

Almost feels a shame to be heading to a new rule set when the field is finding a balance but what a great season we are having.

    Aerodynamics is a huge and very interesting subject. A close friend of mine develops small scale radio controlled speed run cars. Building and racing 1/12, 1/10 and 1/8 scale vehicles at over 100MPH is not as easy as some may think. One current project even uses active giro assisted steering, electronically adjustable spoiler and rear wing providing live micro fine control of aerodynamics and downforce. When You are changing the surface roughness of the paint on specific sections of a body shell to gain an extra one or two MPH You know it's going to be a fun week. Often wished we had a wind tunnel to test the RC cars in as doing all testing and development outdoors, effectively on track R&D, makes it so much harder to get consistent data but after seeing some of the complexity of wind tunnel calibration issues maybe we are better off with live outdoor testing. Always very interesting to hear from professionals who live and breath aerodynamics. Thank You for these excellent videos Sir. Keep up the good work.

    Mercedes' wind tunnel testing issues that caused their F1 dominance to end in 2022 were due to the following reasons:
    Rolling Road Surface Roughness: The team used a smoother Rolling Road surface than the actual track, which led to inaccurate data on how the car's aerodynamics would behave in real-world conditions.
    Limited Testing Time: Mercedes was restricted to 36 wind tunnel runs per week in 2021 due to the aerodynamic testing regulations, which made it difficult to conduct enough reference runs to calibrate their data."
    Focus on Performance over Calibration: In order to maximize their limited testing time, Mercedes prioritized performance testing over calibration runs, which led to further inaccuracies in their data.
    These issues combined to give Mercedes a false sense of confidence in their car's performance, which led to them making poor design choices that ultimately ended their dominance.

    1977: Lotus founder Colin Chapman realized - thanks to a mistake in the manufacture of the side pods of the JPS78 Formula 1 car - that by putting a flexible slat on the bottom outside edge of the side pods, the car cornered significantly faster than without them - as standard F1 cars of the day only had wings for aerodynamic aids at both ends back then. It ultimately led to the JPS79 that gave both Mario Andretti and the late Ronnie Petersen the fastest (if not the most reliable) car in F1 leading to Andretti winning the driver's championship, Petersen (who had passed away from injuries sustained in the Italian GP) posthumously securing second place, and Team Lotus securing the 1978 Constructer's championship.

    What does this teach us: A good driver (like Lewis) only becomes champion if he is backed by the best engineers. If the engineers make a mistake, no matter "how great" that driver is, he cannot push that car to do miracles and win championships. In other words, Lewis was lucky to drive a Mercedes and not a Haas in the years when he won.

    I get why it’s important that the wind tunnel is as smooth and steady as possible, however, that isn’t close to how wind works in real life. So the data may look favourable in the smooth wind tunnel, but they don’t see how the downforce is affected in the buffeting winds outside; which could drastically change the effectiveness of their downforce.

    Turbulent flow isn't that hard to predict, to be honest. The part that really makes it difficult is when you have a laminar flow that transitions to turbulent, because that transition is unsteady. Because it's unsteady and cars depend so much on flow conditioning, that sometimes it's better to simply induce the turbulence yourself. Sometimes consistent but lower energy flow works better than inconsistent but potentially higher energy flow. Better the devil you know, than the one you don't type of thing.

      The same principle is used on the leading edge root extensions you see on fighter aircraft, where they intentionally create a vortex near the wing root to force the air flowing over the wing a bit closer to the wing, which serves the quadruple purpose of creating a vortex of fast flowing air providing a bit of negative pressure which further increases lift at high angles of attack, delaying flow separation past the usual stall points, which improve low speed maneuverability and predictability of the air flowing over the wing at low speeds, and making the plane look cool as hell.
      Some race cars also have vortex generators over convex portions of their exterior for the same purpose - it's better to trip the flow into turbulent flow at a predictable location than to have the transition point vary depending on many tiny factors, some of which are impossible to account for, such as the temperature of the surface or the amount of dirt that has built up on the car since it had last been washed.

    Fascinating to think about that boundary layer on the track surface due to the accelerated air around the car’s bodywork… never would have thought of that. But seems really critical. Also; picked up on a very interesting comment by Adrian Newey in F1 podcast where he casually mentioned the need to think in terms of 3D moreso with the current spec cars… it’s not as intuitive to think that way but the vertical functionally of the floor is so key to the current ground effect cars, I assume.

  • @jeffery7281

    As a college student of aviation engineering, I'm quite curious of why ppl outside the aerospace industry seems *never truly know what is the boundary layer* , even when their machines could have the similar scale, speed of incoming airflow, and Re nunmbers as an aircraft will be.
    Like Ferrari's S-Duct on SF23 last year, and the narrow gap in RB20's undercut tunnel. The moment I saw both of them, my brain was yelling "boundary layer diverter", but many ppl seems like just don't understand what they were for, even in some "technical" blogs or podcasts.
    *Plus:* there's another problem that made Mercedes (and, to be honest, everyone on the grid except Newey) can't find the serious problem of porpoising - the maximum moving speed of model in the tunnel. The car model is not just ride on the ground like what their full-scale reference will do, but instead being loaded via the vertical arms. That basically means the car will be "hanged" just right above the belt, so of course it won't show any evidence of porpoising.
    And, even if the team already knew the porpoising will be a problem, they will still won't be able to simulated this effect in the tunnel - the maximum moving speed of the arm (and the model) is only 1/10 of the actual porpoising frequency!

    Very familiar to terms Laminar flow and Turbulent flow which was defined by Bernoulli, as a Civil engineer its quite good to understand and hear. Great words and terminology are appreciated.

    I can watch a video any length of the dynamics that comes into play on a Formula One car! Hell, I would watch any video involving aerodynamics on just about anything! There’s just something so fascinating about the way fluid fluids! If that makes sense!

    The company I worked in the nineties made the control to get the road running with extreme high precision. Normally side control precision was well below 0.1mm. And tension even more accurate. High tech by itself, even looking so simple.

    Mercedes got used to throwing money at the problem until the cost cap regs arrived. During the 2017 season, they used to have parts that are tailored to specific tracks and outspent Ferrari and RedBull by tens of millions just to beat them.

      Half what you’re saying is true. Yes they threw money at the car. But out spending Ferrari and even RB during those years isn’t true, if that I can assure you. Certainly not by “hundreds of millions”
