Does the Symmetry have anything to do with it, water splashing on hood in a certain spots, both sides of hood

Ok, it's late. But, I had a thought while riding in my brother's old ram charger. It was raining and on both sides of the hood, which is apparently designed the same, left and right, there was one spot near the edge of the hood where water collected and splashed up, he referred to it as a vertex , I don't know how accurate that would be. But, it was sort of obscure, and interesting....anyways.


I was wondering, how do you look at that? It's happening on both sides, both sides are symmetrical...do you say that the Symmetry has nothing to do with the water effect? After all the hood simply is a hood, and it simply is symmetrical and it's a design and there the water effect takes place...

The hood is in its complete physical state, and it exists in this way. We could observe the water effect possibly off of another surface, besides the hood. But in reality it is the hood experiencing the water effect. A major factor of the hood is that it is symmetrical and the water effect is happening on both sides.

Does the symmetry have anything to do with the water effect? Is there a philosophical argument here? Or is their a scientific one? Thoughts?

I'm not sure exactly what you're asking. You want to know what causes water to collect on a certain part of the hood and splash up? And you want to know if the symmetry of the hood has anything to do with that? It's easiest to talk about the car as though it were standing still while a stream of air flows over it. As the air stream meets the hood, it separates into two flows, one to the right and one to the left. Those flows are what is called "laminar," that is, each is like a layer free of turbulence. However, at the front center of the hood, the air doesn't know immediately whether to go to the right or the left. That meeting zone is turbulent, and part of the turbulence takes the form of a pair of vortexes, i.e., circles of air rotating in opposite directions. Water caught in those vortexes can be thrown upward.

I have to say that it takes a special person to notice the phenomenon that you did and to seek an explanation. Out of ten thousand people who see car hoods in the rain, maybe one will be intelligent and astute enough to notice that. A tip of my hat to you! I think you have a bright future.

symmetry is a math idea. look into that
some or most things have a design with left right , up down , triangle etc
you could imagine a fold that matches two sides

part of the idea is rotation. imagine a 5 pointed star, each time it is rotated 1/5 of a turn it is the same
does that make sense

symmetry is a very important idea in physics

keep thinking that is how new discoveries are made

humans are almost, but not quite symmetrical
