Turbulent boundary layers: is the wall falling or merely wobbling?

摘要

A quick passage through five centuries of turbulence research highlights the major milestones. The more recent cornerstones include Kolmogorov’s equilibrium theory of turbulence spectrum, the universal logarithmic law of wall-bounded flows, and the proliferation of direct numerical simulations. Evidence of recent fault lines in all three major achievements is presented, but also novel remedies as well as a few contemporary accomplishments are pointed out.
