law of the wall, horizontal velocity near the wall with mixing length model.

The phrase means an unknown factor, something that causes things to turn out differently than would normally be assumed. Woodpiles used to be stacked loosely with spaces, to avoid rot (see illustration) and were presented by racists as natural hiding places for Black people, where they could either nap (fitting the stereotype of the lazy Black man) or spy on their White neighbors.
