Just asking that, you are not familiar with the horror of turbulence. I put those quotes in for a reason: some very great minds have stared into the abyss of turbulence. The Navier-Stokes equations have a "smoothness problem" where some values sometimes go to infinity. Error bars on infinity ...
- bernulli 5y agoThis makes no sense whatsoever, maybe the abyss has stared back? Turbulent flows can be quite predictable, as the fluctuations smooth out statistically. Even simple turbulence models are quite accurate when it comes to the effect of turbulence, say, in pipe flow, or over flat plates and airfoils. Even for situations in which that is not the case, why would error bars go to infinity? As to the smoothness problem, that may get you to claim a $1,000,000 Millenium prize in mathematics, but plays no role whatsoever in practical simulations.
