Aerodynamics Of A Cow: OpenFoam LES CFD Simulation

We did the most accurate CFD simulation ever to find the aerodynamics of a cow. Using OpenFoam and LES. Find out how aerodynamic a cow is, the Q criterion, and the vortices it produces.

Thank you for this, I don't know what humanity would do without this vital knowledge.

I remember when this meme started. It was a Reddit thread many years ago where a guy did this with a basic aerodynamic software thingy and someone in the comments said he had an open source one that was easier to use and simpler. On a completely different thread, some guy mentioned he always wanted to know the aerodynamics of a lobster to settle a debate. So I hooked these two users up and spent an inordinate amount of time looking for a 3D model of a lobster. The guy put it in the software and it turns out lobsters are quite aerodynamic. I presented the data to the guy and he was surprised I went through the effort for some rando because I was bored and curious as well.

Do humankind know what speed needs a cow to be travelling through the air so that it can fly like a plane?
Thanks for the simulation btw

Did you find out the sensitivity of aerodynamic behavior to the udder size? I hope it is included in the future work if you haven't!

would a splitter improve the downforce of the cow

I'd ask why, but it's obvious, really

I have no idea why the algorithm recommend this to me, but I like it.

What is the drag and lift coefficient of a cow?

[ddboss]

Dang, this cow's got ground effect going on. Red Bull, sign this cow immediately!
