Abstract: Turbulence is an unsolved problem in classical physics. Its modeling often involves physical, mathematical, and numerical concepts that are daunting to even experienced engineers. This makes it very hard for a user to take a turbulence model from the literature and apply it in real-world engineering. This talk will take a layman’s perspective to turbulence modeling. Special attention will be given to near-wall turbulence modeling. We will try to discuss the following two possibilities, both of which are brought to us by colleagues outside the wall modeling community. First, the possibility of breaking the speed-accuracy-tradeoff curse and developing a wall model that effortlessly accounts for non-equilibrium effects. Second, the possibility of giving a layman the ability to make informed decisions as a seasoned engineer when selecting a turbulence model.
