Improving Gas Mileage by Design

05/29/2022 4:30 PM

Golf ball dimples on a car improved it's gas mileage by 11%...How could we incorporate this effect without detracting from the cars appearance?

ThAts be an extreme challenge,,. Especially people suffering from Trypophobia

Many years ago, our family car resembled that one, after a major hailstorm. At the time, with gas at $0.19 a gallon (including full service) we weren't paying much attention to mileage...

Sorry. It doesn't work.

I guess it all depends on who you believe has the most rigorous testing. Anything short of controlled environment dyno/wind tunnel instrumentation testing is probably open to question.

FWIW

The simple simple gives an almost random effect: if the surfaces were designed to give the best effect, then I bet the car would look really cool.

In the video, was the plain car loaded with additional weight to compensate for the weight of the clay?

The way to make this work is to paint the dimples onto a smooth for some idiot who wants more miles per gallon. It is like the "go faster stripes" and oversized exhaust outlets that you see on wannabe cars. The placebo affect could make the driver think that he/she is getting a better mpg.

Sure you could. Sell it on Wish for $50. Make money disappointing wishful thinkers. Wind up on the top 10 list of worst Wish automotive products along with the 12v electric cpu fan cum turbo for your commuter car on Donut.

Tiger Woods might like to drive that one.

HA! He could probably drive that one a lot farther than 300 yards, and wouldn't even need a club!

Nah! He has driven too many holes already.

If Elon drove one,eventually everyone would want one.

A new style trend; Like Jeffro,drinking from the finger bowl.(A nod to the Beverly Hillbillies)

My question is,how small can the dimples be made and still function in air?

Sharks have small dimples in their skin that makes them more hydrodynamic.

Even submarines have started using this effect.

Would there be an optimum speed for best effect?Could dimple size affect the optimum speed?What effect would spacing have on the effect?

How about 1 giant pimple,like a UFO?

I would be willing to research all the variables if I could get a government grant of say, a couple of million dollars to start,for initial set up,and of course,further research would be needed, and another grant.

Perhaps I could start an on line fund?

BE ALERT! (The world need more LERTS!)

I think that's a great question. 3M made a tape with fine ridges that was used to cover the hulls of 12m racing yachts that reduced the drag significantly a few years back. What they found was that the vorticies that occured on the the surface separated the hull drag from the water. The same thing is happening in air with the dimples on a golf ball.

3M got their inspiration for the tape from the small ridges on the belly's of blue whales....

If I remember correctly,there was a swim suit that was designed with small dimples,like shark skin,but it was not allowed in the Olympics because it gave the swimmer an unfair advantage.

Engineers could never quite explain how a bumblebee could fly.There just was not enough wing area or energy available .

As high speed photography advanced and they were able to see what was happening,they saw that the wings flapped in a sort of figure 8 pattern,causing vortexes above the wings that assisted the lift of the wings.

Maybe this effect can be(or has been?) exploited by aircraft by using a dimpled surface?

( Of course,pimpled teenagers cannot run faster than the smooth skins ones..or not.Has a government study been done on this?Can I get a grant for this study?)

Just a thought:Have they tried Fractal Dimples?What would the effect be?Better or worse? Hmm...Jus' thinkin'.

Does the ratio of depth to diameter or spacing have an effect that could be optimized?

Do all golf balls have the same dimple depth and diameter ratio?Does this vary between brands of golf balls?

Perhaps fractal dimples could make a golf ball go further?

More research needs to be done.Maybe Porsche is already doing this.

Wind tunnel testing would give more reliable results,as already stated.

Has anyone spotted a UFO with dimples?

Teenager to father: I've got bad news and good news --- I dented the car, but it is supposed to improve the gas mileage.
