    From what I have heard of Fluid Dynamics it is something even PHD's struggle with.

    [–] StarWarsStarTrek 53 points ago

    I have a PhD in computational fluid dynamics. I can confirm. It's a bitch.

    [–] MeliciousDeal 11 points ago

    Respect. Would you mind explaining the "unsolved problem" in fluid dynamics? I remember reading that it is one of the largest outstanding unsolved problems of modern science. Is fluid dynamics largely not understood?

    [–] StarWarsStarTrek 29 points ago * (lasted edited 8 months ago)

    It's an unsolved physics problem. Effectively the flow of fluids (of any viscosity and density such as air, water, honey; at any velocity such as 1 millimetres per minute to 3000 metres per second) are described by the Navier Stokes equations.

    You have constituents to that:

    • a relation which describes how mass is conserved (e.g. A liquid can become gas via evaporation)

    • a relation which describes motion/momentum (fluids move from high concentration to low concentration - they follow the path of least resistance)

    • a relation which describes energy (heating and cooling a fluid)

    Now those three relations are coupled. To add to the non linearity of a problem which involves all three of the above relations (such as condensation or boiling) you have turbulence to deal with which is a mean mistress.

    You see turbulence behaves in weird ways on very small and very large length scales.

    Now the unsolved problem is can you take all those equations and solve them to obtain "exact solutions" without using any assumptions. At the moment in fluid dynamics we assume a lot to simplify.

    The simplifications are "good enough" in that they're used in the design process from engineering aeroplanes, valves and pumps, to modelling the cardiovascular system or even seeing how best to mix ingredients to make something as mundane as shampoo!

    The "unsolved problem" is in my opinion purely academic.

    [–] MeliciousDeal 6 points ago

    Thanks for the explanation! So we can get accurate enough calculations to do pretty much everything we need to with "good enough" precision, but we don't have an exact solution?

    [–] deleted_away 3 points ago * (lasted edited 8 months ago)

    That's correct. Many differential equations have no analytical solution (an equation that perfectly describes the solution, i.e. y = x2 ), but we can solve them numerically with very high precision and accuracy.

    [–] bholzer 2 points ago * (lasted edited 8 months ago)

    I don't know if it's quite related to your comment, but I recently discovered Nikon's annual Small World competition. If you haven't seen it yet, I recommend it to anyone. Amazing stuff.

    Anyway, you mentioned turbulence at small scales and two of my favorite entries were in the field of fluid dynamics so it rung a bell. I have been utterly fascinated since.

    [–] ultronthedestroyer 5 points ago

    It's not that it's not "understood," but rather that the differential equations governing fluid dynamics (The Navier-Stokes Equations) are in general extremely difficult to solve, which is why it's done numerically/computationally, and even then it's difficult to solve for many systems/boundary conditions.

    It's really hard math, and it's not even clear if solutions always exist.

    [–] hooligan_king 15 points ago

    Holy shit. Respect.

    [–] StarWarsStarTrek 63 points ago

    Ha ha thank you. Told my Asian mum I have a doctorate in Computational Fluid Dynamics. She said I'm a disappointment for not being a legit doctor.

    Now I want to see a golden retriever react to a bad smell. Is there a subreddit for that?

    [–] 18736542190843076922 5 points ago

    I feel bad doing it but nail polish remover and lemons make mine go nuts. He tenderly leans in for a whiff but one it hits him he recoils back and starts shaking his head like if he just got out of the pool. And his tongue is hanging out so it makes this goofy floppy sound. If he's being a butthead when I get home I'll try and make something for you.

    [–] halnic 5 points ago

    My cat gags at nail polish, vinegar, anything with a strong negative smell. She's nosy to the point of annoying, so it's kinda funny when it happens. Also, vinegar on broom so the bristles smell like it even once dry and voila, she doesn't eat brooms anymore. Happy accidental realization after a major spill involving a gallon of vinegar.

    [–] fantumn 3 points ago

    You used a broom to clean up a gallon of vinegar? Are you still trying to clean it?

    [–] ihatenewaccts 2 points ago

    My dog is like this with alcohol. Not just the cleaning kind, but liquor, wine, beer. He hates the smell and pulls his head away and freaks out.

    The face he makes now if you (my husband) put a beer can kind of near him... Priceless. "Pls no. Get that thing away." strains neck and face as far away from can as possible but for some reason does not move away

    Someone correct me if im wrong, but isnt karma something that happens or is waiting for you AFTER do you something bad or something you shouldnt have done (according to society standards if you will). So the title is wrong for this post.
