hey all,
im a physics student and am studying airflow and downforce etc.
and was just wondering if anyone had tried putting a completly flat panel under there car so the bottom is completely smooth.

like a pices of carbon fibre or something that covers the entire underneath of the car from front bumper to back bumper and from side to side?

would be interested to know if anyone has? because the laws of physics tell us that the car would stick too the ground like fuck and would speed the air passing by the car to enable higher speeds to be reached.

:dweeb: another science geek! lol :geek:

Only messing mate, sounds very interesting, can't say i've ever heard of anyone ever doing it though, i would imagine there is a reason why no-one has done it though!

im not saying your wrong, but would you please explain to me why the car would stick like fu*k to the road? im interested to hear this!

[jonnyshaw89]

it is done on ferrari's and lambos!!!

it makes the air flow faster under the car which pulls it down to the ground.

[williamsvts]

most poeple dont have much ground clearance though so a flat sheet under the car could smaah on normal roads.

[S34MER]

i know that but EXPLAIN HOW it does that?! in technical terms!

[VTaaRon]

id have thought it would cause the car to lift if air is forced under the car as you drive surely air pressure under the car is higher i think it would only be noticable if the car was insanly low and had a good air flow over the top of the car like an F1

[SNewham]

It's a good theory, however if not done properly and the air is allowed to be forced up inside the otherside of the "downforce sheet?" then it would more than likely rip it off and be destroyed :P

[SNewham]

i know that but EXPLAIN HOW it does that?! in technical terms!

bloody hell, where's Adsayer when you need him...


banned as usual "NOOB"

[VTaaRon]

i know that but EXPLAIN HOW it does that?! in technical terms!

i dont think it has that much to do with the underside mate think its the flow over the top forces the car down the flat underside creates a lift rather than a down force to counteract the force of the overflow and stop the car being grounded?! just my theory

[hesslevtr]

its only a bloody saxo

[jonnyshaw89]

no it will make the car flow faster under the car then over the car creating a kind of vaccum.

it works trust!!

[saxodan]

its only a bloody saxo

:clapping: best post ive seena all day

ok you do it so we can have a laugh!

isn't that one of those diecast matchbox cars? surely they have to be made like that. Don't think they really think about airflow when designing them.

[SNewham]

sounds familiar..

haha :oops:

[jonnyshaw89]

so ummm

anyone know where i can get a very large piece of carbon fibre??

lol

[Mystic]

Um, thats like a wind-up car.

My mate has a Mitsubishi GTO TT, the underside of their engine bay is smooth plastic, its also got an 'aero spoiler' which lowers the the smooth part, reducing the ground clearence.

wht u mean bout the fogs?

forget it mate, there taking the pish!! :P

it works trust!!

Nice scientific conclusion, you should do well :thumbup:

[saxodan]

*if a car is travelling at the speed of light and it turns his lights on what will happen*

hmmm

[SNewham]

an object cannot travel at the speed of light because it has a mass.

[S34MER]

*if a car is travelling at the speed of light and it turns his lights on what will happen*

hmmm

what cars do you know that can travel at the speed of light which is 186,000 miles/second if im not wrong! lol if i am im sure mr physics boy will correct me! :P

[jonnyshaw89]

woo another guy who knows wht there on about

[saxodan]

what cars do you know that can travel at the speed of light

the 1.1 is pretty nippy once its warmed up

[chloesax]

ooooohhhhhhhh... did someone say physics, science and airflow in the say sentence??? i've just creamed.

[jonnyshaw89]

it certianly is

[chloesax]

who wants the low down on this smooth floors and stuff???

[saxodan]

Untrue :homme:

Everything has a mass even light photon particles

[SNewham]

nippy and fast are two different things ;) This car is so bloody slow, I put my foot down and I have to pray that it will accelerate quick enough for me to not be humiliated by the BMW right up my arse as I try to overtake a 40mph larda on the left.

[jaybiss]

me chloe

add me to msn ;)

love you long time

[chloesax]

depends if we're talking about wave particle duality mofmo ;)

[jonnyshaw89]

:fcuk: who wants the low down on this smooth floors and stuff???

give it to us :fcuk:

love to kick your ass long time mate.

no that's where you are wrong photon particles do not have a mass they just have momentum ;)

[SNewham]

GCSE physics - A
A-Level physics- D. great stuff. lmao...

[saxodan]

depends if we're talking about wave particle duality mofmo ;)

Were not talking about waves and particles so why would that matter?
And is light can be deflected in a wind tunnel by variations in air pressure, which wouldresult in variations in refractive index, thus meaning it has a mass ;)

[S34MER]

this thread is full of nerds :geek: lol im off i feel outta place haha :P

:fcuk:

give it to us :fcuk:

righty... we can describe air flow into two parts:

Laminar flow - straight flow
And turbulent flow - messy flow

Turbulent flow is bad for aerodynamics as its high drag compared with laminar. high drag obviously blows so we dont wanna go there. now imagine flow over a plate (imagine the underside of a saxo) quite lumpy and can be considered not very smooth. this promotes the originally laminar flow to go into turbulent flow and thus high drag again. Now replace that underside with a super smooth plate... this DELAYS (note delays... it doesnt remove) the turbulent flow and thus the overal drag is reduced.


canna get a bo?

[SNewham]

k that wasn't very nice sorry loll :P

[saxodan]

and back to light-

electromagnetic wave (=EMW) does not carry mass, but carries energy

So, this seems to prove that light has mass.The general
conception is - however - that EMW have no mass.
The famous Einstein´s equation E=m.c^2 shows us
that mass is a very concentrated form of energy, as you
know. And EMW is energy.

OWNED

as for the areodynamic shizzle i got sent out that lesson for being a nob

[chloesax]

also we can geek further by talking about 'boundry layer flows', 'compressible flows, 'incompressible flows' yada yada

But im watch Ch5 so it can wait.

why did i chose a computer course :( I miss science

ah well that was a fun mass debate
im of to do some work

laters mofos and drive safe

[jonnyshaw89]

see i was right all along!!!

all u who doubted should be shamed!!!
lol

cheers chloe!!!

[SNewham]

How the hell can you think that light has a mass? the theory of relativity would be smashed if that was the case... Light has no mass.

[chloesax]

no probs sexyboy x x x

never doubted but definetely wouldnt do it to saxo lol.

wave particle duality (again)

[Mystic]

yah yah yah, i done A-level physics too so shnizzle. On topgear they put duct tape over all the places where there were imperfections in shell of a car. i.e. everywhere panels, windows, doors meet etc. It had a pretty substantial effect on the aerodynamics of the car.

So i say, lets put the books away and go get to work with the gaffer tape! :D:

[SNewham]

no probs sexyboy x x x

you just met him like 5 mins ago. nice one add me to msn hun :oops:

[jonnyshaw89]

they cant resist :P

see buy a saxo 1.1 and girls think u got a big cock

[SNewham]

wave particle duality (again)

yes I wasn't doubting the fact that they can sometimes appear as a wave and aparticle, however that does't prove the point that they have a mass. Maybe you are referrring to the relativistic mass and not actually the rest mass.


really scraping the can empty here.

[SNewham]

they cant resist :P

see buy a saxo 1.1 and girls think u got a big cock

of course, they like a bit of 4 inch inwardly rolled sportex as well

[jonnyshaw89]

lol classic

[RAFkev]

back to the sucking to the floor idea -

gotta talk aircraft principles here - planes fly cos the air across the upper surface of a wing moves faster than the air across the lower surface. this gives a lower pressure on the upper surface (faster moving air) creating lift. once the pressure difference is sufficient (above a certain air-speed) the plane takes off. my point is, if the air is sped up under the car (from less drag due to a plate covering everythin) the faster moving air should create a lower air pressure hence pulling the car to the ground. whether a saxo could reach a speed where the pressure would be enough to actually make this happen is anyones guess!! my guess is no!!

[sy_VTR]

i dont know much about physics, but i would of thought by putting a panel under the car, it will just balance the air flow under the car, as a normal car will have all the exhaust and bits of things that will disturb the air flow under the car,(because the air will catch all the pipework and stuff) dont think it is will hold it down, thinks its just to create even air flow under the car. i could be wrong but thats my theory!

[saxoash]

nice bit of reading :Y:

Just to tell you guys if you didnt know Chloesax is a ladyboy btw lol!
