I really apreciate that post. I posed the question initially because those vanes seemed to me to be just flow directors (or conditioners) as stated in your final sentance. I had not appreciated how little votices on a surface could actually delay the stall of a surface.flyboy2160 wrote:the vortex generators (vgs) are like little dams placed at an angle to the flow. they force the air up and over them or around them, causing a swirl, like a little tornado. you can see this swirl start in a close up of flow over a simple angled plate shape: http://i227.photobucket.com/albums/dd67 ... pswirl.jpg
the swirl pulls air above the surface - which has more velocity - down to the surface where the air has 'lost' velocity. this added velocity helps keep the air from separating off the surface.
you have to play with the size, shape, and location of these things. here's a shot showing my initial placement of some vgs on a wing:http://i227.photobucket.com/albums/dd67 ... 6alpha.jpg
without them, the 'bad' blue air separated right about where the little vortex generator is sticking up. it helped keep the flow attached a little longer. that is the blue area is father back, but the flow still separates.
the vgs on the top of the sidepods are probably trying to do the same thing - keep the flow attached to the sidepod upper surface instead of having it separate.
hope this helps explain a litlle better......
edit: i say 'probably,' because some of the little wing shapes on top of the sidepods may just be flow directors, not neceassarily vortex generators.
Thanks!turbof1 wrote:That would be the airflow coming through the sidepods entrances and the airbox in the roll hoop. Generally, you want that airflow as undisturbed as possible. The more it is disturbed, the more drag you have. Furthermore, you don't want the internal flow to cause low pressure, which as aforementioned creates lift. So you want the air fast in, fast out; just enough for cooling (and air for the engine). The flow will also most likely get heated up and energized, so you want that air to exit the internals at a place where it can produce downforce. Hence the red bull solution: ALL of the internal airflow exits at the back of the coke bottle out of the bulged opening, right onto the beam wing and monkey seat.
It's difficult to tell how teams exactly manage internal airflow. It is always looking for a compromise between packaging, which benefits external airflow, meeting the minimum required
what i expect? that the suspension withstands this powers. recall sutil´s flying force india (fly kingfisherclipsy1H wrote:this isn't a car failure.... was absolutely normal... what you can expect when he hit with over 140 kph the kerb? if you look closely you'll see that he touched grass first and after hit the curb and between these two is a difference in height.winth304 wrote: found this on youtube: http://www.youtube.com/watch?feature=pl ... gsNA#t=55s
imho a suspension should withstand such driving "incidents" more than a schumacher or hamilton overdrivers the engine.
and about downforce... you can't find downforce over nightin last 3 years downforce was the main problem for them (beside tires issue). For a good downforce you need a good aerodynamic package
So this is the reason why i don't believe to much in Mercedes this year... with almost no regulation change it's almost impossible to come in 3 months with an amazing car. In last 4-5 races car was over 2 sec off the pace. Like Lewis said new parts will bring time but with new parts comes all teams. Will be amazing if this year they can win more than 3-4 races (i said 3 because even last year they could win at least 2 if Michael didn't have that crap penalty in Monaco)

Don't forget updated exhaust channels. This is where I expect the most work (not neccesarily visual) work done. Some carefully crafted detailing upstream to tweak the exhaust flow can make a big difference in terms of downforce and tyre wear.dren wrote:I'm going to guess:
